No one knows how the removal of the US weapons sale embargo on Vietnam will result in practice. In Southeast Asian cooperation terms, it might be useful to observe the actions of Singapore -- that trade/services hub doubling as a US aircraft carrier parked by the Strait of Malacca. Singapore happens to perform a superb balancing act between Washington and Beijing. Russia, by the way, is also officially neutral on all matters South China Sea.
China is the top trading partner of the overwhelming majority of Southeast Asia and Northeast Asia nations. It is a prominent member of the East Asia Summit. It is driving its own, Asian-based response to the Obama administration's Trans-Pacific Partnership (TPP) pet project; the Regional Comprehensive Economic Partnership (RCEP).
Beijing knows that the "principled security network" proposed by lame duck Pentagon head Ash Carter in Singapore has no chance whatsoever of becoming a Southeast Asian NATO.
What this all means is that the notion of an "isolated" China does not even qualify as a bad joke told at a stuffy Council on Foreign Relations meeting.
And that brings us back to what happens after the arbitration in The Hague. Something very Asian; Beijing and Manila will sit down again and try to reach a deal, without ever bothering to refer to the ruling. Face will be saved on both sides. China will continue to go mobile -- in search of all that oil and gas.
And count on the Pentagon to continue its meddling.
