Thai Boon Roong Twin Tower World Trade Center

Thai Boon Roong Twin Tower World Trade Center, is a planned skyscraper complex in Phnom Penh, Cambodia, consisting of twin 133-storey skyscrapers with a height of 567 m. The project is managed by the Cambodian company Thai Boon Roong Group, with the Macau-based Sun Kian Ip Group as co-developer. It is planned to be built on a 5 hectare property in the Doun Penh section, formerly occupied by the Dreamland amusement park, and was approved for construction in February 2016. 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; at this time, the building's announced height was 560 m.

Described since then as what would be Southeast Asia's tallest building, 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. Upon completion, the Thai Boon Roong Twin Towers would surpass the Petronas Towers as the world's tallest twin skyscraper (as of 2023 ).

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