Chinese Foreign Minister Wang Yi said to U.S. Secretary of State Marco Rubio that Taiwan is the biggest risk factor in bilateral relations [1, 2].

The exchange occurs as both nations prepare for a high-level summit in Beijing between President Donald Trump and President Xi Jinping [1, 2]. This conversation signals the primary friction point that could disrupt diplomatic efforts to stabilize the relationship between the world's two largest economies.

Wang Yi and Rubio spoke during a phone conversation held either Thursday or Friday [1, 2]. The discrepancy in timing between reports from Mirror Now and Reuters suggests the call took place within the last 48 hours [1, 2].

During the call, Wang Yi said Beijing's position is that the issue of Taiwan poses the greatest risk to the overall tone and direction of U.S.-China relations [1, 2]. The warning emphasizes China's view that U.S. policy toward the island remains a non-negotiable red line for the Chinese government.

The discussion serves as a precursor to the upcoming Beijing summit [1, 2]. By establishing this position early, Beijing is signaling that any progress on trade, or security, may be contingent on the U.S. approach to Taiwan.

Rubio and Wang Yi's exchange highlights the continued tension over sovereignty and strategic influence in the Asia-Pacific region [1, 2]. The two diplomats are tasked with managing these volatile dynamics before the heads of state meet in person.

Taiwan is the biggest risk factor in China–U.S. ties

This exchange underscores that despite efforts to engage in high-level diplomacy, the status of Taiwan remains the primary obstacle to a stable U.S.-China relationship. By framing Taiwan as the 'biggest risk factor' immediately before a presidential summit, China is attempting to set the agenda and warn the U.S. that any perceived interference in Taiwan could derail broader diplomatic or economic agreements.
