TAIPEI (Taiwan News) — US officials on Tuesday said they have seen no changes to the Six Assurances and are working to accelerate delayed arms deliveries to Taiwan, amid renewed scrutiny after comments by US President Donald Trump.

In February, Trump said he had discussed arms sales to Taiwan with Chinese leader Xi Jinping, raising concerns about potential violations of the Six Assurances, per CNA. A White House official told CNA at the time that US policy toward Taiwan remains unchanged.

The US House Foreign Affairs Committee on Tuesday held a hearing titled “Reforming America’s Defense Sales.” US Deputy Assistant Secretary of State for Political-Military Affairs Stanley L. Brown, Under Secretary of Defense for Acquisition and Sustainment Michael P. Duffey, and Director of the Defense Security Cooperation Agency Michael F. Miller testified as lawmakers raised questions about arms sales to Taiwan.

Representative Sarah McBride noted that, following Trump's call with Xi in February, the White House is reportedly delaying two arms packages for Taiwan totaling NT$478.56 billion (US$15 billion). Brown denied any delay, saying, "In the last 90 days, we have moved US$11.1 billion to Taiwan.”

Asked by Representative Ami Bera whether the State Department had taken any steps to alter the Six Assurances related to Taiwan arms sales, Brown said he was not aware of any such changes. He added that under the framework of the US-China Three Joint Communiques and the Six Assurances, “We have stated that we will provide Taiwan what they need for their own self-defense,” he said.

Brown pointed to a NT$353.93 billion arms sale package announced in December, saying the process remains on track. Duffey also said he was not aware of any changes within the Department of Defense regarding the Six Assurances.

Representative Andy Barr asked how the US could speed up the delivery of roughly NT$669.71 billion in backlogged weapons for Taiwan. Barr also noted that the issue has been a key topic during his previous visits to Taiwan.

Brown said the US is exploring ways to accelerate deliveries for arms sales already contracted with Taiwan, many of which involve F-16 fighter jets. He stressed that the government will continue pushing forward on the issue.
