WILL the United States' rejection of the East Asia Economic Caucus (EAEC), mooted by Malaysia, cause the caucus to die a natural death, or will it instead rip apart the Asia-Pacific Economic Co-operation (APEC)? Since Malaysian Prime Minister Mahathir Mohamad mooted EAEC in 1990, it has been a hard slog getting all the countries of East Asia to embrace the concept without reservations.
Fear of antagonising the US, especially on the part of South Korea and Japan, has been the main stumbling block to EAEC's launch.
And the problem does not end there. China, while being supportive, also opposes the inclusion of Taiwan and Hong Kong in the initial phase of EAEC, but has left the door open for their future participation.
EAEC is envisaged as including the six members of the Association of Southeast Asian Nations (ASEAN) - Singapore, Malaysia, Indonesia, Brunei, the Philippines and Thailand - plus Japan, South Korea, China, Taiwan and Hong Kong.
All are members of APEC, which also includes the US, Canada, Australia, Mexico and Papua New Guinea.
Washington had expressed misgivings about EAEC on the grounds that the caucus could evolve into an exclusivist trading bloc but, until last month, stopped short of opposing it unequivocally.
