Washington urged to show caution

China has urged the United States to observe promises it made in the three China-US joint communiques and handle Taiwan-related issues cautiously and properly, after US Secretary of State Rex Tillerson voiced his government's commitment to the one-China policy but also its intentions to keep its commitments to Taiwan.

Foreign Ministry spokesman Lu Kang made the comment on Thursday, saying the one-China principle is the political foundation of China-US ties and is clearly stipulated in the three joint communiques between the two countries.

Tillerson was quoted by Reuters as saying on Wednesday that the Trump administration is committed to the one-China policy but it also intends to keep its commitments to Taiwan.
