This report features the development of economic zones in ASEAN. This is a welcome follow-up to the ASEAN Guidelines for Special Economic Zones Development and Collaboration adopted by ASEAN Economic Ministers (AEM) in 2016. ASEAN has at least 1,600 economic zones of various types. These zones, ranging from free trade zones, export processing zones, IT parks to mega special economic zones, have played a significant role in the socioeconomic development in the region and in attracting FDI. Given the rapid economic growth and demand, ASEAN Member States continue to develop more economic zones to boost FDI. Policy makers, entrepreneurs, and other stakeholders may find this Report useful in understanding economic zones in ASEAN, as well as the business and investment development in the region in general.
