US and China agree on AI safety channel and military crisis talks

China and the U.S. agreed to establish a channel for handling AI-related incidents and accelerate military crisis communications following a three-day summit between their leaders in Washington, both sides announced Saturday. The two nations also agreed to continue cooperation on a trade board addressing selected bilateral issues, with the White House confirming the board began operating this week. No major breakthroughs were reported, but experts noted the working groups could help prevent disputes from escalating. Chinese President Xi Jinping returned to Beijing Saturday after the visit, during which President Donald Trump was notably warm despite the prior year's trade war. Both sides pledged to sign a memorandum on military crisis communications, hold an AI-specific dialogue in November, and extend a trade truce by two months.
