Thai Boon Roong Twin Tower World Trade Center

Thai Boon Roong Twin Tower World Trade Center,[1][note 1] is a planned skyscraper complex in Phnom Penh, Cambodia, consisting of twin 133-storey skyscrapers with a height of 567 m (1,860 ft).[4] The project is managed by the Cambodian company Thai Boon Roong Group, with the Macau-based Sun Kian Ip Group as co-developer.[5][6] It is planned to be built on a 5 hectare property in the Doun Penh section, formerly occupied by the Dreamland amusement park,[7][8] and was approved for construction in February 2016.[9][10] In December of that year, the developers entered a $2.7 billion construction contract with Chinese firms Wuchang Shipbuilding Industry Group and Sino Great Wall International Engineering, who formed a joint venture for this purpose;[7][11][12] at this time, the building's announced height was 560 m (1,840 ft).[7]

Described since then as what would be Southeast Asia's tallest building,[4][13][note 2] if built, the twin skyscrapers would be the second tallest buildings in the region—after Merdeka 118, which is nearing completion in 2023 and has a height of 678.9 m (2,227 ft). Upon completion, the Thai Boon Roong Twin Towers would surpass the Petronas Towers as the world's tallest twin skyscraper (as of 2023[15]).

In mid-2017, 1 August 2017 was set as the date of the start of construction.[16] Since then, construction has been delayed multiple times.[17][7][18] A groundbreaking ceremony was held on the site in 2018,[19] however, later that year, Sino Great Wall International Engineering withdrew from the project due to concerns over financing and citing "greater uncontrollable risks."[20] As of 2022, the project has been "failing to materialize", according to Southeast Asia Globe,[21] and, as of 2023, the Council on Tall Buildings and Urban Habitat website lists the project's status as "proposed".[1] The company has cited the COVID-19 pandemic as a reason for the delay.[4][22]
