Indonesia–Malaysia–Thailand Growth Triangle

The Indonesia–Malaysia–Thailand Growth Triangle (IMT-GT) is a subregional economic cooperation framework established to accelerate economic transformation, enhance connectivity, promote balanced growth and strengthen cooperation among its member provinces and states. It was officially established in 1993 by Indonesia’s President Soeharto, Malaysia’s Prime Minister Mahathir Mohamad, and Thailand’s Prime Minister Chuan Leekpai, representing one of ASEAN’s earliest initiatives to promote cross-border economic integration.

Anchored on shared geography, culture, and economic complementarities, IMT-GT fosters private-sector-driven integration and people-centered development across borders. It seeks to stimulate sustainable and inclusive development across 35 provinces and states within the three participating countries, an area covering approximately 683,300 km² and home to over 96 million people.
