China's bonus can only be placed in SE Asia if Vietnam Revolts was triggered

[Tuch-o]

Quoting Ramko:

If the USSR has Vietnam Revolution during the turn, and plays China in Southeast Asia, the regional bonus gets locked to Southeast Asia, you get the option to use 2 regional bonus placements, but you can't place them outside of SE Asia to be clear, im referrign to the regional bonus from China, the regional bonus from Vietnam Revolution is meant to only be used in SE Asia, but the China one gets locked into SE asia as well
