US and Asian economic architecture?

Comments on Claude Barfield “Where is the U.S. in Asia’s future?” 9/02/2010, http://www.eastasiaforum.org/2010/02/09/where-is-the-u-s-in-asias-future/

Claude Barfield argues: "The TPP, a trade and economic agreement among four nations (New Zealand, Chile, Singapore, and Brunei) was signed in 2005. As a vehicle for the United States to advance its interests in Asia, it has a number of attractions."

One cannot help asking a question: how many of those economies belong to Asia and how much does that represent Asia's economic weight?

Perhaps it might be a good starting point to influence the economic architecture of Asia, one has to wonder?

It is really very scholarly indeed!
