Chinese authorities have condemned the U.S. for arranging the “stopover” of Taiwan regional leader Lai Ching-te. The Chinese side reiterates the Taiwan question is one of China's core interests and it is the first red line that cannot be crossed in China-U.S. relations. Experts share their opinions on issues such as the Taiwan politician’s intentions with the stopover, the sensitivity of the Taiwan question in China-U.S. relations and potential policies of the new U.S. government regarding Taiwan.
