Taiwan’s Foreign Ministry said Tuesday, September 29, that U.S. policy toward Taiwan remains unchanged. The statement came after U.S. Ambassador to China David Perdue told Fox News on Sunday that President Donald Trump had asked Chinese leader Xi Jinping whether he wanted to buy U.S. weapons.

Trump disputed the account on Monday, saying the issue had not been discussed and suggesting Perdue may have been referring to Taiwan.

Speaking at a press briefing on Tuesday, Foreign Ministry Deputy Spokesperson Chen Yi-chun (陳怡君) said Perdue made it clear in his interview that U.S. policy toward Taiwan will not change. Chen added that this reflects a longstanding position repeatedly reaffirmed by the Trump administration.

Perdue had also reiterated Washington’s commitments under the Taiwan Relations Act and the Six Assurances, the deputy spokesperson said.

The U.S. State Department also appeared to distance the administration from Perdue’s remarks, according to the Associated Press. The department said in a statement provided to U.S. media that U.S. law prohibits arms sales to China and that there was “no offer or plan” to sell arms to Beijing.

Chen said China is undermining regional stability. Taiwan will continue working with the United States and other like-minded countries to maintain stability and security in the Taiwan Strait and the wider region, she added.
