"If you have two or three different agreements, it is difficult for businesses to deal with rules, especially for the SMEs [small and medium-sized enterprises]. So they will have to merge," Julius Caesar Parrenas, a member of the APEC Business Advisory Council, said.
According to Parrenas, the controversial Trans-Pacific Partnership (TPP) is only one of several regional multilateral trade agreements. He cited the example of the Regional Comprehensive Economic Partnership (RCEP) regulating trade between the Association of Southeast Asian Nations (ASEAN) members.
The RCEP is a 16-nation negotiation on a trade area between 10 ASEAN states and the six non-ASEAN regional countries, including Australia, China, India, Japan, Korea, and New Zealand. According to ASEAN data, RCEP states make up some 30 percent of the world economy.
