May 21 (UPI) — President Donald Trump has said he will speak with Taiwanese President Lai Ching-te about a stalled $14 billion arms deal, a call that would be precedent-setting for a sitting U.S. president and likely anger China.

“I’ll speak to him,” Trump said Thursday from the tarmac of Joint Base Andrews in Maryland.

The president was responding to a reporter’s question on whether he planned to call Lai before making a final decision on the Congress-cleared weapons deal, the future of which remains uncertain following Trump’s visit last week to Beijing for meetings with Chinese leader Xi Jinping.

Taiwan has requested the weapons package as it faces an aggressive China, which claims sovereignty over the self-governing island it views as a breakaway province and has said it will take it back by force if necessary.

The weapons deal was pre-approved by Congress in January 2025, and Taiwan’s legislative body earlier this month approved a special defense budget of $25 billion to buy weapons from the United States. The package now requires Trump to sign off on it.

But Trump on Friday told reporters aboard Air Force One while en route back to the United States following his visit with Xi in Beijing that they had “talked a lot about Taiwan” and that he would “make a determination over the next fairly short period” on whether to give the arms deal final approval.

Taiwan was a significant topic during the trip, with Xi warning Trump that the island was “the most important issue” in bilateral ties and that, if mishandled, could trigger “clashes and even conflicts.”

Amid the uncertainty, Lai issued a Facebook post Sunday night stating Taiwan-U.S. security cooperation and arms sales “are key elements in maintaining regional peace and stability” and that the island’s security is the region’s security.

Trump did not say Wednesday when he would speak with Lai or discuss specifics concerning the arms deal.

“We have that situation very well in hand,” he said, adding that he had an “amazing” meeting with Xi.

“We’ll work on that,” he said.

Trump spoke with Taiwan’s then-President Tsai Ing-wen in 2016, when he was the president-elect, but no sitting U.S. president is known to have spoken with the leader of Taiwan since Jan. 1, 1979, when the Carter administration formally severed diplomatic ties with the Republic of China, the official name of Taiwan’s government, and established relations with the People’s Republic of China in Beijing.

Spokeswoman Zhu Fenglian of Beijing’s State Council Taiwan Affairs Office gave reporters a standard answer during a press conference Wednesday, stating: “We firmly oppose the United States conducting any form of official exchanges with China’s Taiwan region, and we firmly oppose the United States selling weapons to China’s Taiwan region.”

“This position is consistent and clear,” she said.

UPI has contacted Taiwan’s Foreign Ministry for comment.

Democrats and some Republicans have urged Trump to approve the arms deal and expressed concern over its future as the president was in Beijing.

“Trump must not sell out Taiwan, period,” Senate Minority Leader Chuck Schumer, D-N.Y., said in a social media statement.

The Republic of China, the current government of Taiwan, once governed mainland China but retreated to the island following its defeat by the Chinese Communist Party in the Chinese Civil War in 1949.

The Chinese Communist Party views Taiwan as part of China under its One China principle and seeks reunification with the island — an act Taiwan says would amount to an illegal annexation.
