WASHINGTON (AP) — President Donald Trump has demonstrated greater ambivalence toward Taiwan in his second term. That’s raising questions about the Republican president’s commitment to maintaining American support for the self-ruled island ahead of this week’s summit with Chinese President Xi Jinping.

In December, Trump authorized an $11 billion arms package for Taiwan but delayed its delivery and discussed the sale with Xi.

Trump said Monday he expects Xi will ask him to hold back on arming Taiwan.

Trump has accused Taiwan of “stealing” America’s semiconductor business and pressured it to invest in U.S. tech sectors. Analysts say Xi might urge Trump to loosen ties with Taiwan, which Beijing views as its breakaway province.
