Seriously though, old hatreds, and ones passed down generations never die. Asian communists seem to be long term haterz.

It isn't about Communists - WWII is not over in any of the countries Japan brutalized, and China is still mad at Britain over the Opium Wars. China is staging a five act drama over the THAAD deployment in South Korea and stirring up their native population with an anti-Korean propaganda campaign worthy of a CNN profile on Trump.
Vietnam would be a useful military ally in the region, and I think they would abandon the last vestiges of Communism far more quickly than China has if given the opening to do so. Have you seen Saigon, lately?
