North-East Asian economic integration

Comments on Andrew Elek “North-East Asian economic integration: APEC or FTA games?” 17/11/2010, http://www.eastasiaforum.org/2010/11/17/north-east-asian-economic-integration-apec-or-fta-games/
While many of Andrew's arguments are undoubtedly valid in an ideal world, he only mentioned but ignored the implications of NAFTA on other regional preferential agreements.

Further, it is difficult to understand why the three governments could not see the advantages and disadvantages of a North-East Asian FTA that Andrew has in mind.

It is a question of who failed to understand what.
