China Threatens to Cancel US-China Leaders’ Summit Over Potential Taiwan Arms Sale
By Drooid · · How we work
Core Event
Chinese officials have warned that they will call off a planned US-China leaders’ summit later in September if Washington approves any additional arms sales to Taiwan before the September 12 deadline. The summit, slated for September 24, would host President Donald Trump and President Xi Jinping together at the White House. The warning follows a record-setting US arms package for Taiwan announced in December 2025.
Background & Context
Under the Taiwan Relations Act of 1979, the United States supplies Taiwan with weapons to maintain a sufficient self-defence capability. In December 2025, the Trump administration announced an US $11 billion (S$14 billion) arms sales package to Taiwan, the largest ever. During a May 14 meeting in Beijing, President Xi told President Trump that Taiwan was the “most important issue” in bilateral ties and cautioned that mishandling it could spark conflict. Trump later described the arms sales as a “very good bargaining chip” in negotiations with China, linking the issue to his broader diplomatic agenda ahead of the November midterm elections.
Official Statements & Responses
Chinese sources reiterated that the Taiwan question is a “red line” in US-China relations and that any new arms approval before September 12 would trigger cancellation of the summit. The Chinese government has not issued a formal announcement regarding President Xi’s visit. President Trump has publicly invited Xi to the United States on September 24 and plans a state dinner for the Chinese leaders. In parallel, the United States is intensifying economic sanctions on Iran, prompting reports that Beijing is willing to coordinate with Washington on that issue.
Data & Statistics
- US $11 billion arms sales package to Taiwan (December 2025) – the highest-valued sale to date.
- September 12 – deadline by which Chinese officials say approval of further sales will lead to summit cancellation.
- September 24 – scheduled date for the White House summit, pending China’s decision.
What’s Next
If Washington proceeds with additional arms sales before September 12, Chinese officials are prepared to cancel the September 24 summit. Conversely, if no new sales are approved, the summit is expected to proceed as planned, potentially addressing other agenda items such as US-Iran sanctions coordination.
