The diplomatic tensions between the United States and China have escalated due to the U.S.'s planned arms sale to Taiwan, valued at approximately $20 billion, which includes significant defense systems. According to Express News, China has issued a stern warning to the U.S., stating that this move could jeopardize President Donald Trump's scheduled visit to China in April 2026. Beijing has emphasized that the arms sale could become a 'serious obstacle' in Sino-American relations, particularly in the context of the upcoming diplomatic engagements. President Xi Jinping reportedly communicated to President Trump via phone, expressing that such actions could negatively impact bilateral relations, as China views Taiwan as an integral part of its territory and perceives foreign arms sales as a threat to its sovereignty and regional peace.
