President Donald Trump said on Friday he hasn't decided whether to proceed with a major weapons sale to Taiwan, adding to uncertainty about U.S. support for the island after his trip to China.
Trump also implied he would speak with Taiwan's president about the proposed sale, an interaction that could shake U.S.-China relations.
A direct conversation between a sitting U.S. president and Taiwan's leader would be unprecedented since 1979 and would likely anger China.
Trump told reporters aboard Air Force One: "I have to speak to the person that is running Taiwan." He did not name President Lai Ching-te.
A senior administration official reiterated that a determination on a new arms sale would be made "in a fairly short" time.
Under U.S. law, Washington is required to provide Taiwan with the means to defend itself. Lawmakers from both parties have urged the administration to continue weapons sales.
A major arms package worth up to $14 billion, including advanced interceptor missiles, awaits Trump's approval. His efforts to secure a trade deal with China had raised concerns he could curb military support.
During talks, Xi Jinping warned that mishandling Taiwan could lead to conflict. Trump said he made no commitments and declined to answer whether the U.S. would defend Taiwan.
Taiwan's Foreign Ministry thanked Trump for past sales, emphasizing they are a security commitment under the Taiwan Relations Act.
