China and US clash again on trade and regional security

China and the United States clashed again this weekend on trade and security, accusing each other of destabilizing the region and potentially the world.

Speaking on Sunday at the Shangri-La Dialogue in Singapore, Asia’s premier defense summit, China’s Defence Minister Wei Fenghe warned the United States not to meddle in security disputes over Taiwan and the South China Sea.

On Saturday, acting U.S. Defense Secretary Patrick Shanahan told the meeting that the United States would no longer “tiptoe” around Chinese behavior in Asia.

“Perhaps the greatest long-term threat to the vital interests of states across this region comes from actors who seek to undermine, rather than uphold, the rules-based international order,” Shanahan said.

It was the latest exchange of acerbic comments between the two sides as their ties come under increasing strain due to a bitter trade war, U.S. support for Taiwan and China’s muscular military posture in the South China Sea, where the United States also conducts freedom-of-navigation patrols.

China has been particularly incensed by recent moves by President Donald Trump’s administration to increase support for self-ruled and democratic Taiwan, including U.S. Navy sailings through the Taiwan Strait that separates the island from China.
