The past week was nothing but eventful considering the relative peace China-US relations have enjoyed since Chinese President Xi Jinping and his US counterpart Donald Trump struck a constructive note for bilateral ties when they met in Mar-a-Lago, Florida, in April.

Over the past few days, Washington has approved a $1.4-billion arms sale to Taiwan and blacklisted a Chinese bank for alleged business ties with the Democratic People's Republic of Korea, and the US Senate Armed Services Committee has approved a bill for US naval vessels to make regular stops at Taiwan ports and help the island develop undersea warfare capabilities.

The moves run counter to the consensus reached by the two presidents on that occasion that the two countries should work together to forge a constructive partnership.
