China urged the United States on Thursday to honor promises it made over the Taiwan question and stop military contact with Taiwan immediately to avoid damaging China-US ties.

Foreign Ministry spokesman Lu Kang made the remarks at a daily news conference in Beijing in response to a question on a bill amended by the US Senate Committee on Armed Services. The amendment allows the US Navy to make regular port calls in Taiwan.

The bill, the National Defense Authorization Act for Fiscal Year 2018, shows that the committee amendment "reestablishes regular ports of call by the US Navy at Kaohsiung or any other suitable ports in Taiwan, and permits the US Pacific Command to receive ports of call by Taiwan".
