The Indonesia–Malaysia–Thailand Growth Triangle (IMT-GT) comprises five priority economic corridors that are key geographic areas for subregional economic cooperation under the IMT-GT. This Malaysia country report draws on findings of a study that reviewed and assessed the five existing economic corridors as well as a proposed sixth economic corridor. The report provides data and analysis of the corridors from a national perspective, with a focus on physical connectivity, trade, and value chains. It also looks at relevant strategies and plans for the provinces involved in economic corridor development.
