The Indonesia-Malaysia-Thailand Growth Triangle (IMT-GT) is a subregional cooperation initiative formed in 1993 by the governments of Indonesia, Malaysia, and Thailand to accelerate economic and social transformation in less developed provinces. Since its formation, IMT-GT has grown in geographic scope and activities to encompass more than 83 million people. It is now composed of 14 provinces in southern Thailand, 8 states of Peninsular Malaysia, and the 10 provinces of Sumatra in Indonesia. IMT-GT is also growing in importance outside of its subregion. The ASEAN Secretariat (ASEC) has recognised IMT-GT as a building block for the ASEAN Community Vision 2525.
