The Golden Triangle Special Economic Zone (Lao: ເຂດເສດຖະກິດພິເສດສາມຫຼ່ຽມຄຳ, Chinese: 金三角经济特区; pinyin: Jīnsānjiǎo Jīngjìtèqū, abbreviated GTSEZ) is located along the Mekong River in the Ton Pheung District of Bokeo Province in Laos. The zone has an area of about 3,000 hectares; it was created in 2007 by the Lao government together with the Hong Kong-registered company Kings Romans Group, with the stated goal of generating regional economic development.
At the centre of the zone is the Kings Romans casino and several hotels, which attracts mostly Chinese visitors. The local infrastructure is de facto Chinese, Mandarin is widely spoken and the Chinese yuan is the preferred currency. It is part of a wider trend of casinos emerging in the Mekong region, following the displacement of money laundering activities from Macao in 2014.
