Globalization has increasingly made economic diplomacy a key component of foreign policy. Since production decisions made by Transnational Corporations (TNCs) are influenced by various domestic factors, the role of host governments has become important, for example, in keeping transaction costs low. Participating in free trade agreements (FTAs) that go beyond trade and include non-tariff barriers, government procurement, competition policy, and intellectual property protection is one key mechanism for keeping such costs low and through this attract foreign direct investment (FDI).

FTAs involving ASEAN countries have introduced a structured and government-to-government form of cooperation that is redefining the balance of economic power. This can be observed in the growing number of such arrangements that symbolizes not only greater economic opportunity but also closer political ties. ASEAN states have adapted to this new trend of diplomacy at four levels (global, transregional, regional and bilateral) and its related strategic and political alignments. The positive effects of growing ASEAN economic diplomacy, in addition to lowering business costs, are also observed in technology and skills transfer and infrastructure investment.

Economic diplomacy is said to have its advantages. It generates higher economic growth, efficiency, transparency and ease of doing business in a country. However, its benefits face risks as well. Going forward, one should note that economic diplomacy is a dynamic process that changes with new realities. However, to succeed in economic diplomacy, a country needs a skilled pool of policymakers and private sector actors who can understand and negotiate key economic and trade issues. For the ASEAN economies, assuming the status quo, as long as they continue to deliver on robust economic growth and there is a cooperative stance towards each other, economic diplomacy can be seen as a “positive-sum” game in the years to come.
