Iran–Russia relations

Derbent is renowned for the Sassanid Iranian fortress, a UNESCO World Heritage Site.

Contacts between Russians and Persians have a long history, extending back more than a millennium.[12] There were known commercial exchanges as early as the 8th century AD between Persia and Russia.[1] They were interrupted by the Mongol invasions in the 13th and 14th centuries but started up again in the 15th century with the rise of the state of Muscovy. In the 9th–11th century AD, there were repetitive raiding parties undertaken by the Rus' between 864 and 1041 on the Caspian Sea shores of what are nowadays Iran, Azerbaijan, and Dagestan as part of the Caspian expeditions of the Rus'.[13] Initially, the Rus' appeared in Serkland in the 9th century traveling as merchants along the Volga trade route, selling furs, honey, and slaves. The first small-scale raids took place in the late 9th and early 10th century. The Rus' undertook the first large-scale expedition in 913; having arrived on 500 ships, they pillaged the Gorgan region, in the territory of present-day Iran, and the areas of Gilan and Mazandaran, taking slaves and goods.

It was not until the 16th century that formal diplomatic contacts were established between Persia and Russia, with the latter acting as an intermediary in the trade between England and Persia. Transporting goods across Russian territory meant that the English could avoid the zones under Ottoman and Portuguese control.[1] The Muscovy Company (also known as the Russian Company) was founded in 1553 to expand the trade routes across the Caspian sea.[1] Moscow's role as an intermediary in exchanges between Britain and Persia led Russian traders to set up business in urban centres across Persia, as far south as Kashan.[1] The Russian victories over the Kazan Khanate in 1552 and the Astrakhan Khanate in 1556 by Tsar Ivan IV (r. 1533–84) revived trade between Iran and Russia via the Volga-Caspian route and marked the first Russian penetration of the Caucasus and the Caspian area.[12] Though these commercial exchanges in the latter half of the 16th century were limited in scope, they nonetheless indicate that the fledgling entente between the two countries emerged as a result of opposition to the neighboring Ottoman Empire.

Diplomatic relations between Russia and Iran date back to 1521, when the Safavid Shah Ismail I sent an emissary to visit the Czar Vasili III. As the first diplomatic contacts between the two countries was being established, Shah Ismail was also working hard with the aim of joining forces against their mutual enemy, neighboring Ottoman Turkey.[1] On several occasions, Iran offered Russia a deal exchanging a part of its territory (for example Derbent and Baku in 1586) for its support in its wars against their Ottoman archrivals.[1] In 1552–53, Safavid Iran and the Muscovy state in Russia exchanged ambassadors for the first time, and, starting in 1586, they established a regular diplomatic relationship. In 1650, extensive contact between the two people, culminated in the Russo-Persian War (1651–53), after which Russia had to cede its footholds in the North Caucasus to the Safavids. In the 1660s the famous Russian Cossack ataman Stenka Razin raided, and occasionally wintered at, Persia's north coast, creating diplomatic problems for the Russian Czar in his dealings with the Persian Shah.[14] The Russian song telling the tragic semi-legendary story of Razin's relationship with a Persian princess remains popular to this day.

Peace reigned for many decades between the two peoples after these conflicts, in which trade and migration of peoples flourished. The decline of the Safavid and Ottoman state saw the rise of Imperial Russia on the other hand. After the fall of Shah Sultan Husayn brought the Safavid dynasty to an end in 1722, the greatest threats facing Persia were Russian and Ottoman ambitions for territorial expansion in the Caspian region—north-western Persia specifically. During the Safavid period, Russian and Persian power was relatively evenly balanced.[1] Overall, the common anti-Ottoman struggle served as the main common political interest for Iran and Russia throughout the period of Safavid rule, with several attempts to conclude an anti-Ottoman military treaty.[12] Following Shah Husayn's fall, the relationship lost its symmetry, but it was largely restored under Nader Shah.[1]

In his later years of rule, Peter the Great found himself in a strong enough position to increase Russian influence more southwards in the Caucasus, the Caspian Sea and the Black Sea, challenging both the Safavids and the Ottomans. He made the city of Astrakhan his base for his hostilities against Persia, created a shipyard, and attacked the weakened Safavids in the Russo-Persian War (1722–1723), capturing many of its territories in the Caucasus and northern mainland Iran for several years. After several years of political chaos in Persia following the fall of the Safavids, a new and powerful Persian empire was born under the highly successful military leader Nader Shah. Fearing a costly war which would most likely be lost against Nader and also being flanked by the Turks in the west, the Russians were forced to give back all territories and retreat from the entire Caucasus and northern mainland Iran as according to the Treaty of Resht (1732) and Treaty of Ganja (1735) during the reign of Anna of Russia. The terms of the treaty also included the first instance of close Russo-Iranian collaboration against a common enemy, in this case the Ottoman Turks.[15][16] Relations sooned soured, however, after Nader Shah accused the Russians of conspiring against him. The invasion of Dagestan in 1741 was partially directed against Russia; thus the Terek River was left on a high state of alert until Nader Shah's death.[17][18]

Karim Khan Zand promised the Russians certain territories in the northern frontier if they helped him against enemies like the Ottomans.[19]

Irano-Russian relations particularly picked up again following the death of Nader Shah and the dissolution of his Afsharid dynasty which gave eventually way to the Qajarid dynasty in the mid-18th century. The first Qajar Persian Ambassador to Russia was Mirza Abolhassan Khan Ilchi. After the rule of Agha Mohammad Khan, who stabilized the nation and re-established Iranian suzerainty in the Caucasus,[20] the Qajarid government was quickly absorbed with managing domestic turmoil, while rival colonial powers rapidly sought a stable foothold in the region. While the Portuguese, British, and Dutch competed for the south and southeast of Persia in the Persian Gulf, the Russian Empire largely was left unchallenged in the north as it plunged southward to establish dominance in Persia's northern territories. Plagued with internal politics, the Qajarid government found itself incapable of rising to the challenge of facing its northern threat from Russia.

The Battle of Ganja (1804) during the Russo-Persian War (1804–1813).

A weakened and bankrupted royal court, under Fath Ali Shah, was forced to sign the notoriously unfavourable Treaty of Gulistan (1813) following the outcome of the Russo-Persian War (1804–1813), irrevocably ceding what is modern-day Dagestan, Georgia, and large parts of the Republic of Azerbaijan. The Treaty of Turkmenchay (1828) was the outcome of the Russo-Persian War (1826–1828), which resulted in the loss of modern-day Armenia and the remainder of the Azerbaijan Republic, and granted Russia several highly beneficial capitulatory rights, after efforts and initial success by Abbas Mirza failed to ultimately secure Persia's northern front.[21] By these two treaties, Iran lost swaths of its integral territories that had made part of the concept of Iran for centuries.[22] The area to the north of the Aras River, which included the territories of the contemporary nations of Georgia, Azerbaijan, Armenia and the North Caucasian Republic of Dagestan, were Iranian territory until they were occupied by Russia in the course of the 19th century.[23][24][25][26][27][28] Russia more or less openly pursued a policy to free their newly conquered land from Iran's influence. By doing this, the Russian government helped to create and spread a new Turkic identity that, in contrast to the previous one, was founded on secular principles, particularly the shared language. As a result, many Iranian-speaking residents of the future Azerbaijan Republic at the time either started hiding their Iranian ancestry or underwent progressive assimilation. The Tats and Kurds underwent these integration processes particularly quickly.[29]

Anti-Russian sentiment was so high in Persia during that time that uprisings in numerous cities were formed. The famous Russian intellectual, ambassador to Persia, and Alexander Pushkin's best friend, Alexander Griboyedov, was killed along with hundreds of Cossacks by angry mobs in Tehran during these uprisings. With the Russian Empire still advancing south in the course of two wars against Persia, and the treaties of Turkmanchay and Golestan in the western frontiers, plus the unexpected death of Abbas Mirza in 1823, and the murder of Persia's Grand Vizier (Abol-Qasem Qa'em-Maqam), Persia lost its traditional foothold in Central Asia.[30] The Treaty of Akhal, in which the Qajarid's were forced to drop all claims on Central Asia and parts of Turkmenistan, topped off Persian losses to the global emerging power of Imperial Russia.

In the same period, by a proposal of the Shah with the backing of the Tsar, the Russians founded the Persian Cossack Brigade, which and would prove to be crucial in the next few decades of Iranian history and Irano-Russian relations. The Persian Cossacks were organized along Russian lines and controlled by Russian officers.[31] They dominated Tehran and most northern centers of living. The Russians also organized a banking institution in Iran, which they established in 1890.[32]

During the 19th century, Russians dealt with Iran as an inferior "Orient", and held its people in contempt whilst ridiculing all aspects of Iranian culture.[33] The Russian version of contemporaneous Western attitudes of superiority differed however. As Russian national identity was divided between East and West and Russian culture held many Asian elements, Russians consequently felt equivocal and even inferior to Western Europeans. In order to stem the tide of this particular inferiority complex, they tried to overcompensate to Western European powers by overemphasizing their own Europeanness and Christian faith, and by expressing scornfully their low opinion of Iranians. The historian Elena Andreeva adds that this trend was not only very apparent in over 200 Russian travelogues written about Iran and published in the course of the 19th and early 20th centuries, but also in diplomatic and other official documents.[33]

In 1907, Russia and Britain divided Iran into three segments that served their mutual interests, in the Anglo-Russian Convention of 1907.[31] The Russians gained control over the northern areas of Iran, which included the cities of Tabriz, Tehran, Mashad, and Isfahan. The British were given the southeastern region and control of the Persian Gulf, and the territory between the two regions was classified as neutral territory.

Russia's influence in northern Iran was paramount from the signing of the Anglo-Russian Convention of 1907 until the outbreak of World War I in 1914.[33] During this time period, it stationed troops in Iran's Gilan, Azerbaijan and Khorasan provinces, and its diplomatic offices (consulates) in these parts wieleded considerable power. These consulates dominated the local Iranian administration and in some circumstances even collected local taxes. Starting in the same year as the Anglo-Russian Convention, unpremeditated Russian colonization commenced in Mazandaran and Astarabad provinces. Then, in 1912, Russian foreign policy officially adopted the plan to colonize northern Iran. At the outbreak of World War I, there were most likely some 4,000 Russian settlers in Astarabad and Mazandaran, whereas in northeastern Iran the Russians had founded a minimum of 15 Russian villages.[33]

During the reign of Nicholas II of Russia, Russian occupational troops played a major role in the attempted Tsarist suppression of the Iranian Constitutional Revolution.[3][33] In the dawn of the outbreak of World War I, Russian occupational forces occupied Qajar Iran's Azerbaijan province as well as the entire north and north-east of the country, and amounted to circa twenty thousand.[34] Following the start of the Persian Campaign of World War I, the number of Russian troops in Iran moderately grew to some eighty or ninety thousand.

As a result of the major Anglo-Russian influence in Iran, at a high point, the central government in Tehran was left with no power to even select its own ministers without the approval of the Anglo-Russian consulates. Morgan Shuster, for example, had to resign under British and Russian diplomatic pressure on the Persian government. Shuster's book The Strangling of Persia: Story of the European Diplomacy and Oriental Intrigue That Resulted in the Denationalization of Twelve Million Mohammedans is an account of this period, criticizing the policies of Russian and Britain in Iran.[35]

These, and a series of climaxing events such as the Russian shelling of Mashad's Goharshad Mosque in 1911, and the shelling of the Persian National Assembly by the Russian Colonel V. Liakhov, led to a surge in widespread anti-Russian sentiments across the nation.

Colonel V. Liakhov was notorious for shelling the National Iranian Assembly in 1911.

One result of the public outcry against the ubiquitous presence of Imperial Russia in Persia was the Constitutionalist movement of Gilan, which followed up the Iranian Constitutional Revolution. Many participants of the revolution were Iranians educated in the Caucasus, direct émigrés (also called Caucasian muhajirs) from the Caucasus, as well as Armenians that at the same period were busy with establishing the Dashnaktsutyun party as well as operations directed against the neighboring Ottoman Empire. The rebellion in Gilan, headed by Mirza Kuchak Khan led to an eventual confrontation between the Iranian rebels and the Russian army, but was disrupted with the October Revolution in 1917.

As a result of the October Revolution, thousands of Russians fled the country, many to Persia. Many of these refugees settled in northern Persia creating their own communities of which many of their descendants still populate the country. Some notable descendants of these Russian refugees in Persia include the political activist and writer Marina Nemat and the former general and deputy chief of the Imperial Iranian Air Force Nader Jahanbani, whose mother was a White émigré.

Russian involvement however continued on with the establishment of the short-lived Persian Socialist Soviet Republic in 1920, supported by Azeri and Caucasian Bolshevik leaders. After the fall of this republic, in late 1921, political and economic relations were renewed. In the 1920s, trade between the Soviet Union and Persia reached again important levels. Baku played a particularly significant role as the venue for a trade fair between the USSR and the Middle East, notably Persia.[36]

In 1921, Britain and the new Bolshevik government entered into an agreement that reversed the division of Iran made in 1907. The Bolsheviks returned all the territory back to Iran, and Iran once more had secured navigation rights on the Caspian Sea. This agreement to evacuate from Iran was made in the Russo-Persian Treaty of Friendship (1921), but the regaining of Iranian territory did not protect the Qajar dynasty from a sudden coup d'état led by Colonel Reza Shah.[31]

In the 1920s-1930s, the Soviet secret service (Cheka-OGPU-NKVD) carried out clandestine operations on Iranian soil as it tried to eliminate White émigrées that had moved to Iran.[37] In 1941, as the Second World War raged, the Soviet Union and the United Kingdom launched an undeclared joint invasion of Iran, ignoring its plea of neutrality.

In a revealing cable sent on July 6, 1945, by the Central Committee of the Communist Party of the Soviet Union, the local Soviet commander in northern Azerbaijan was instructed as such:

"Begin preparatory work to form a national autonomous Azerbaijan district with broad powers within the Iranian state and simultaneously develop separatist movements in the provinces of Gilan, Mazandaran, Gorgan, and Khorasan".[38]

After the end of the war, the Soviets supported two newly formed in Iran, the Azerbaijan People's Government and the Republic of Mahabad, but both collapsed in the Iran crisis of 1946. This postwar confrontation brought the United States fully into Iran's political arena and, with Cold War starting, the US quickly moved to convert Iran into an anti-communist ally.

The Soviet Union was the first state to recognize the Islamic Republic of Iran, in February 1979.[39] During the Iran–Iraq War, however, it supplied Saddam Hussein with large amounts of conventional arms. Supreme Leader Ayatollah Khomeini deemed Islam principally incompatible with the communist ideals (such as atheism) of the Soviet Union, leaving the secular Saddam as an ally of Moscow. However, during the war, the USA imposed an arms embargo on Iran, and the Soviet Union supplied arms to Iran via North Korea.

After the war, in 1989, Iran made an arms deal with Soviet Union.[40] With the fall of the USSR, Tehran–Moscow relations experienced a sudden increase in diplomatic and commercial relations, and Russia soon inherited the Soviet-Iranian arms deals. By the mid-1990s, Russia had already agreed to continue work on developing Iran's nuclear program, with plans to finish constructing the nuclear reactor plant at Bushehr, which had been delayed for nearly 20 years.

During the East Prigorodny conflict, and Georgian–Ossetian conflict, Iran secretly supported Ossetian separatism against Georgia, and sided with the Ossetians against Ingush and Chechens in the conflict.

As tension between the United States and Iran escalates, the country is finding itself further pushed into an alliance with Russia, as well as China. Iran, like Russia, "views Turkey's regional ambitions and the possible spread of some form of pan-Turkic ideology with suspicion".[41]

Prior to the Iranian revolution Iran's air fleet was entirely Western-made but in the 21st century Iran's Air Force and civilian air fleet are increasingly becoming domestically and Russian-built as the US and Europe continue to maintain sanctions on Iran.[42][43][44]

In May 2007 Iran was invited to join the Collective Security Treaty Organization, the Russia-based international treaty organization that parallels NATO.[9][45] The invitation came from the desk of then CSTO Secretary-General Nikolai Bordyuzha, who said that "the CSTO is an open organization. If Iran applies in accordance with our charter, we will consider the application." It was stated by a Western observer that the accession failed "basically due to the ayatollahs’ opposition to join a military bloc clearly dominated by a traditionally rival power of Iran such as Russia."[45] Another Western observer points out that, like NATO, CSTO has a mutual defense treaty clause whereby attack against one is considered an attack against all and was concerned about the difficulty posed by a possible conflagration of the Iran-Israel variety.[9] In November 2014 Sluzhba Vneshney Razvedki head Sergey Naryshkin floated the idea of admitting Iran as an observer to the CSTO Parliamentary Assembly.[9][46]

In 2010, Iran's refusal to halt uranium enrichment led the UN to pass a new resolution, number 1929 to vote for new sanctions against Iran which bans the sale of all types of heavy weaponry (including missiles) to Iran. This resulted in the cancellation of the delivery of the S-300 system to Iran:[47] In September 2010 Russian President Dmitry Medvedev signed a decree banning the delivery of S-300 missile systems, armored vehicles, warplanes, helicopters and ships to Iran. Mahmoud Ahmadinejad criticised Russia for kowtowing to the United States.[48] As a result of the cancellation, Iran brought suit against Russia in Swiss court and in response to the lawsuit Russia threatened to withdraw diplomatic support for Iran in the nuclear dispute.

Since the outbreak of the Syrian civil war in 2011, Iran and Russia have become the Syrian government's principal allies in the conflict, openly providing armed support. Meanwhile, Russia's own relations with the West plummeted due to the Russo-Ukrainian War, the 2018 Skripal poisoning incident in Great Britain, and alleged Russian interference with Western politics, prompting the U.S. and Europe to retaliate with sanctions against Russia. As a result, Russia has shown a degree willingness to ally with Iran militarily. Following the JCPOA agreement, President Vladimir Putin lifted the S-300 ban in 2015 and the deal for the missile defense system to Iran was revived.[49] The delivery was completed in November 2016 and was to be followed by a $10 billion deal that included helicopters, planes and artillery systems.[50]

In January 2021 Iran, China and Russia held their third joint naval exercise, the third joint exercise of the three countries, in the northern Indian Ocean and the Sea of Oman area. The joint exercise of the three countries began in 2019 in the Indian Ocean.[51]

According to the United States, Russia sought to acquire drones from Iran during the Russo-Ukrainian War, with a Russian delegation visiting Kashan Airfield south of Tehran in June and July 2022 to observe drones manufactured by Iran.[52] Iran criticized the assessment by the United States, saying that it would not supply Russia or Ukraine with military equipment during the war, instead demanding that both nations seek a peaceful resolution.[53] In September 2022, the Ukrainian military claimed that it encountered an Iranian-supplied suicide drone used by Russia, publishing images of the wreckage of the drone.[54] On October 6, 2022, Iran agreed to provide "additional" surface to air missiles and drones to Russia.[55] On October 24, 2022, Iranian Foreign Minister Hossein Amirabdollahian said Iran would "not remain indifferent" if it is "proven that Iranian drones are being used in the Ukraine war against people," but claimed defense cooperation between Iran and Russia would continue.[56]

According to various media outlets, as of 2023, the American intelligence has claimed that Iran has been assisting Moscow in building a drone factory within its borders to maintain its war machine in Ukraine.[57][58]

In August 2023, The White House has reportedly urged Iran to cease selling armed drones to Russia as part of broader discussions in Qatar and Oman, aimed at de-escalating the nuclear crisis. This effort runs alongside negotiations for a prisoner exchange deal, which recently led to the transfer of Iranian-US citizens from prison to house arrest. The US seeks to prevent Iran from supplying drones and spare parts to Russia, currently used in the Ukrainian conflict.[59]

Iran is a CSTO candidate

Russia and Iran also share a common interest in limiting the political influence of the United States in Central Asia. This common interest has led the Shanghai Cooperation Organisation (SCO) to extend to Iran as observer status in 2005, and offer full membership in 2006. The Iranians attained full membership status on 17 September 2021.[60] Moscow and Beijing supported Tehran's successful bid for full membership in the SCO.[61]

Iran and Russia have co-founded the Gas Exporting Countries Forum along with Qatar.

In addition to their trade and cooperation in hydrocarbons, Iran and Russia have also expanded trade ties in many non-energy sectors of the economy, including a large agriculture agreement in January 2009 and a telecommunications contract in December 2008.[62] In July 2010, Iran and Russia signed an agreement to increase their cooperation in developing their energy sectors. Features of the agreement include the establishment of a joint oil exchange, which with a combined production of up to 15 million barrels of oil per day has the potential to become a leading market globally.[63] Gazprom and Lukoil have become increasingly involved in the development of Iranian oil and gas projects.

In 2005, Russia was the seventh largest trading partner of Iran, with 5.33% of all exports to Iran originating from Russia.[64] Trade relations between the two increased from US$1 billion in 2005 to $3.7 billion in 2008.[62] Motor vehicles, fruits, vegetables, glass, textiles, plastics, chemicals, hand-woven carpet, stone and plaster products were among the main Iranian non-oil goods exported to Russia.[65]

In 2014, relations between Russia and Iran increased as both countries are under U.S. sanctions and were seeking new trade partners. The two countries signed a historic US$20 billion oil for goods deal in August 2014.[66][67][68]

In 2021, trade between the nations rose 81% to a record $3.3 billion.[69]

President Ebrahim Raisi, who was elected in 2021, seemed to prioritize trade with Russia.[61] In early 2022, Ebrahim Raisi traveled to Russia at the invitation of his Russian counterpart. He handed over Iran's proposed draft for a 20-year cooperation agreement between Iran and Russia during his trip.[61]

With the invasion of Ukraine in February 2022 by Russia, the U.S. and other nations have imposed sanctions on Russia.[70] In the opinion of at least one Western writer, in order to evade sanctions, Iran and Russia could be working together to create a "clandestine banking and finance system to handle tens of billions of dollars in annual trade banned under U.S. led sanctions."[71]

On 20 March 2022 it was reported that Iran, in the person of Agriculture Minister Javad Sadatinejad, had signed a deal in Moscow with Russia to import 20 million tons of basic goods including vegetable oil, wheat, barley and corn.[72]

In May 2022 Deputy Prime Minister Alexander Novak and Iranian Oil Minister Javad Owji, joint co-chairs of the Russian-Iranian Intergovernmental Commission had a meeting in Tehran at which they discussed such items as oil swaps, increasing joint investments, a possible free trade zone, adding to the Russian-built Bushehr Nuclear Power Plant, and developing the long-delayed North-South Transport Corridor, a rail cargo route from all the way from Russia to India, among other items.[69]

Russian President Vladimir Putin visited Tehran on 19 July 2022 to meet with his Iranian counterpart Ebrahim Raisi and Turkey's Recep Tayyip Erdogan. The Turkish president was previously involved to mediate in the 2022 Ukraine conflict. The three nations have been holding talks in recent years as part of the "Astana peace process" to end more than 11 years of civil war in Syria. Iran and the Russian Federation attempt to boost economic ties after being hit by Western sanctions.[73]

In December 2022, Russia and Iran announced a new transcontinental trade route from the eastern edge of Europe to the Indian Ocean. The passage spans 3,000-kilometers and could be established beyond the reach of Western sanctions. Russia and Iran share similar economic pressures amid sanctions – and both look east to integrate their growing economies.[74]

In early February 2023, Tehran and Moscow announced they fully linked the Russian Financial Messaging System of the Bank of Russia (SPFS) with Iran's SEPAM national financial messaging service; both countries had been excluded from SWIFT. Bilateral economic ties had intensified since sanctions were placed on Russia after the 2022 Russian invasion of the Ukraine, and chances for the revival of the JCPOA with Iran faded in late 2022. In 2022/23, Russia with US$2.7 billion is by far the largest investor in the sanctioned Iranian economy. As both countries face dramatically devalued currencies, Russia and Iran aim to link their payment system to larger economies such as India and China.[75]

In May 2023, the US said that Iran and Russia are working to build more drones which will be used against Ukraine.[57]

In June 2023, Iran's Transport Minister, Mehrdad Bazrpash, announced plans to create a joint shipping company with the Russian Federation. Iran places great emphasis on the importance of the Volga and Caspian Seas for trade with Russia. Both countries have reached a quadrilateral agreement with Uzbekistan and Turkmenistan regarding the transit of oil products and grain.[76]

As Iran and Russia economic and geo-political relations have improved over the years, Russia and the Eurasian Economic Union (EEU) have opted for Iran to join the EEU as well. Currently, only one EEU country, Armenia, shares a land border with Iran, but the Caspian Sea provides a direct link between Iran and Russia.

Iran has expressed interest in joining the EEU. A meeting between Kazakhstan President Nursultan Nazarbayev and Iranian President Hassan Rouhani was held in 2015 to discuss the prospect of cooperation between the customs union and Iran. According to the Iranian Ambassador to Russia, Mehdi Sanaei, Iran is focusing on signing an agreement with the EEU in 2015 regarding mutual trade and reduction of import tariffs to central Asian countries and trading in national currencies as part of the agreement rather than in US dollars.[77]

In May 2015, the Union gave the initial go-ahead to signing a free trade agreement with Iran. Andrey Slepnev, the Russian representative on the Eurasian Economic Commission board, described Iran as the EEU's "key partner in the Middle East" in an expert-level EEU meeting in Yerevan. Viktor Khristenko furthermore noted that Iran is an important partner for all the EEU member states. He stated that "Cooperation between the EEU and Iran is an important area of our work in strengthening the economic stability of the region".[78]
