Remanufacturing policies have been gradually introduced in Asian countries, such as China, Japan, Malaysia, Singapore, and Thailand. This paper reviews the process of diffusion of remanufacturing policy in Asia. The mechanism of this diffusion is also discussed. The United States began to promote the idea of remanufacturing around the year 2000 through bilateral free trade agreements with Asian countries and international forums such as G8 and the Asia-Pacific Economic Cooperation (APEC). This paper reviews the various efforts on remanufacturing in Asian countries and discusses policy options for promoting remanufacturing. It is crucial to identify the ways to promote remanufacturing in each country in the region to improve resource efficacy and strengthen the circular economy in Asia.
