President Xi Jinping warned his U.S. counterpart, Joe Biden, in a phone call Thursday against “external interference” in Beijing’s dealings with the island.
China says Taiwan has no right to conduct foreign relations. It sees visits by American officials as encouragement for the island to make its decades-old de facto independence official.
The Ministry of Defense warned Washington this week not to allow Pelosi, who is Biden’s equal in rank as leader of one of three branches of government, to visit Taiwan. A spokesman said the PLA would take unspecified “strong measures” to stop pro-independence activity.
The PLA has flown growing numbers of fighter planes and bombers near Taiwan and has in the past fired missiles into shipping lanes to the island.
Taiwan and China split in 1949 after a civil war that ended with a communist victory on the mainland.
The two governments say they are one country but disagree over which is entitled to national leadership. They have no official relations but are linked by billions of dollars in trade and investment.
