Secretary of State Marco Rubio stated on Wednesday, Sept. 23, 2026, that a pause in U.S. arms sales to Taiwan is necessary to balance the nation’s industrial capacity and military needs in other regions. Speaking at the United Nations General Assembly, Rubio, who also serves as President Donald Trump's national security adviser, noted that providing equipment to one partner means it is unavailable for U.S. forces or other global commitments.
The statement follows a letter from four Republican senators, led by Mitch McConnell (R-Ky.), who urged the administration to release security assistance for Taiwan. The senators noted that the administration is currently withholding $14 billion in foreign military sales and $300 million in foreign military financing, while the Pentagon has not obligated $1 billion for the Taiwan Security Cooperation Initiative.
Rubio said that while the U.S. has sufficient munitions for objectives in Iran, Washington must account for obligations to NATO, the Indo-Pacific, and Southern Command. He emphasized that the industrial base and domestic military needs are primary factors in the decision-making process. President Trump previously characterized the $14 billion sale, which was approved by Congress in January, as a "negotiating chip" during talks with Chinese President Xi Jinping.
For observers of regional security, critics argue this shift in policy represents a departure from the "Six Assurances," a set of pledges established during the Reagan administration to maintain Taiwan's defense without negotiating the terms with Beijing. A person in Taiwan or a U.S. treaty ally like Japan or the Philippines would notice a change in the perceived stability of the Indo-Pacific, as the delivery of rocket systems, missiles, and howitzers is delayed. A person in the U.S. might see the effects in the long-term prioritization of domestic military stockpiles over foreign exports.
The broader U.S. alliance network in the Pacific is monitoring Washington’s willingness to fulfill defense commitments. What happens next depends on the outcome of the summit between President Trump and President Xi Jinping scheduled for later this week, as the $14 billion sale cannot proceed until the president formally transmits it to Congress.
