@osu888:
Does this change the rule with the Mongolian units? Can Russia not do this?
If Russia liberates Korea or any originally Chinese territory that borders any of the Mongolian territories, then the Mongolians will never become Soviet even if later Japan takes one of the originally Soviet territories bordering Mongolia (e.g. Amur)
@osu888:
Also, after Japan is at war with UKP, is it true that China cannot move units into UK controlled countries as extra defense?
Chinese units can always move into Burma or Kwangtung, but not into other territories that are outside mainland China
