Biden's national security adviser holds talks with China's top diplomat in Beijing

US National Security Adviser Jake Sullivan has arrived in China for his first visit, aiming to stabilize relations between the two countries. Sullivan will meet with Chinese Foreign Minister Wang Yi, following a high-stakes summit between Presidents Xi Jinping and Joe Biden in January. The visit comes amid tensions between China and its neighbors, particularly Japan and the Philippines, over the South China Sea. Japan has scrambled fighter jets after a Chinese military aircraft entered its airspace, while the Philippines has accused China of being the "biggest disruptor" in the region. Sullivan and Wang Yi have expressed hopes for productive talks, but the situation remains tense, with Japan and the Philippines blaming China for raising regional tensions.
