ROC & RPC can never co-exist, read the constitutions before you shout.  If ROC gains the supports and recognition as RPC at the moment, I believe the ROC gov't will do the same towards RPC.  How can a country allow another "country" who claims to own the same land exist in the world?  It is impossible.  The only way to get around it is to change the constitutions...  but of course you've got to "prepare" for the results...
