Beijing calls for US to stick to core of one-China policy

China has urged the United States to refrain from having any official contact with Taiwan, thus harming China-US ties, after the US House of Representatives passed a bill encouraging visits between US and Taiwan officials.

The Taiwan Travel Act, which was passed by the House on Tuesday, has yet to be passed by the US Senate and signed by President Donald Trump to become law.

Foreign Ministry spokesman Lu Kang expressed on Thursday China's firm opposition to the bill. "The bill violates gravely the one-China policy and the principles established in the three China-US joint communiques, and is an interference into China's internal affairs," Lu said at a daily news conference.
