In 1979, the “Three Noes”: no contact, no compromise, no negotiation, with the PROC was adopted in response to the ROC's “Three Links” and maintained by president Kuo.

In 1987, an Open Door policy allowed the ROC Red Cross to issue permits for people from Taiwan to travel to their relatives in the mainland, prompting the start of ongoing civilian exchanges between the ROC and the PRC.
