"We urge the United States side to strictly abide by the one-China principle and the three China-U.S. joint communiques, immediately stop any form of official contacts between the United States and Taiwan, prudently handle Taiwan-related issues, and refrain from sending any wrong signals to the 'Taiwan independence' separatist forces so as to avoid further damage to China-U.S. relations and peace and stability across the Taiwan Strait," the spokesperson said.
