Chinese Foreign Minister Wang Yi told U.S. official Marco Rubio that Taiwan represents the biggest risk to relations between the two nations [1, 2].
The exchange underscores the fragility of the diplomatic relationship as Beijing continues to view any U.S. support for Taiwan as a violation of its core interests. This tension remains the primary obstacle to broader cooperation on global security and economic stability.
During a telephone call between Beijing and Washington in April 2026 [1], Wang Yi said that the Taiwan issue is central to China's national security. The minister said, "the Taiwan issue concerns China’s core interests" [1].
Wang Yi urged the U.S. government to maintain its previous commitments to ensure stability. He said that the United States should keep its promises and make the right choices in order to open up new space for China-U.S. cooperation and work for world peace [2].
Reports on the exact timing of the call varied, with some sources citing Thursday and others citing Friday [1, 2]. Similarly, descriptions of Marco Rubio's role differed across reports, with some identifying him as the new U.S. Secretary of State and others as a U.S. Senator [1, 2].
Wang Yi said that Taiwan is the biggest risk in ties [2]. He suggested that the path toward world peace depends on the United States recognizing these boundaries and avoiding actions that provoke Beijing.
“"The Taiwan issue concerns China’s core interests."”
The communication reflects a strategic attempt by China to set strict boundaries for the new U.S. administration. By framing Taiwan as the 'biggest risk,' Beijing is signaling that no matter the progress made in trade or climate cooperation, the status of Taiwan remains a non-negotiable red line that could trigger a systemic collapse of diplomatic relations.
