No room for further uncertainty about the US stance on Taiwan
The US has been sending mixed signals about its Taiwan policy. But a decision not to send senior American officials to the opening of its new de facto embassy in Taipei is an example of the sensitivity on this issue needed to keep bilateral relations with China on track

Respect for the one-China principle is essential to constructive dialogue with Beijing. US President Donald Trump was reminded of that soon after he took office in the wake of comments that pointed to Taiwan being used as a bargaining chip in negotiations on trade.
This led to Beijing freezing top-level communications. It took a pledge from Trump to honour the policy to fully thaw them.
Amid efforts to head off a looming China-United States trade war and heightened tension across the Taiwan Strait, there is no room for further uncertainty over the American stance on what China sees as a core issue.
It is regrettable, therefore, that the US now appears to be sending mixed signals about its Taiwan policy.
