President Donald Trump warned the UK and Canada against striking business deals with China, after British Prime Minister Keir Starmer became the latest US ally to announce plans to deepen trade ties during a visit to Beijing.

Chinese President Xi Jinping has had a busy few weeks receiving Western allies seeking warmer ties with the world's second-largest economy. Canadian Prime Minister Mark Carney struck a trade deal slashing tariffs on Chinese electric vehicles and Canadian canola oil.

Starmer is on a 4-day visit to China this week, the first trip by a British leader in eight years, signaling an attempt at resetting the bilateral ties.

President Trump warned the U.K. it is “very dangerous” to deepen ties with China after PM Keir Starmer met Xi Jinping in Beijing, also cautioning that Canada faces even greater risk.
