Four Ifs

The Four Ifs are a set of preconditions developed by Chen Shui-bian clarifying and tempering the stance of Taiwan's Democratic Progressive Party (DPP) regarding independence for the island. They were developed in 1988 by Chen, under the Kuomintang administration of Lee Teng-hui. They indicate events which, if occurred, would cause the DPP to immediately advocate for independence for Taiwan.

They are:

• If the Kuomintang unilaterally holds talks with the Chinese Communists;
• If the Kuomintang sold out the interests of the people of Taiwan;
• If the Chinese communists annexed Taiwan;
• If the Kuomintang did not implement true constitutional democracy.
