3. RCEP

The Regional Comprehensive Economic Partnership, comprised of 10 ASEAN nations as well as China, Japan, South Korea, Australia and New Zealand, is the world's largest free-trade agreement.

Accounting for roughly 30 percent of the world's population, GDP and trade, the RCEP countries create the world's largest free trade bloc by economic size, making it the biggest driver of global economic growth.

Hong Kong enjoys close trade and investment relations with the economies of RCEP, including FTAs with 13 of the 15 founding nations in the RCEP accord. It plays an important role in merchandise trade between ASEAN and the Chinese mainland.

Opportunities will abound once the special administrative region joins the RCEP. It will cultivate deeper economic and trade integration with the Asia-Pacific region.
