In all honesty, the concern over the Asian Pacific region and trade is somewhat premature. Trump likes Russia, so the issue is will Russia continue it's movement into isolationism or not? Then there is China and it's relationship to the region. In my opinion, as noted with the Philippines, China is already isolating and claiming it's sovereign territory. As of today, it seems to me the 'Family of Nations' is a faux security to financial stability. 

If Congress agrees with all Trump's musings the world will be a very different place by the year 2016. 

I sincerely believe China and Russia are already isolationist powers in transition from globalization.
