Days before Donald Trump’s expected visit to Beijing, China has issued a firm message to the United States, placing Taiwan at the center of tensions. Chinese Foreign Minister Wang Yi, in a call with US Secretary of State Marco Rubio, stressed the need to maintain stability while warning that Taiwan remains the most sensitive issue in bilateral ties. Beijing described it as a core interest and cautioned Washington to make careful choices. The exchange comes as both sides prepare for high-level talks, with global concerns ranging from Iran tensions to energy supply disruptions shaping the backdrop. The upcoming Trump-Xi meeting is seen as a crucial moment to manage differences and prevent further escalation in an already fragile geopolitical environment.
