U.S. President Donald Trump has warned Britain against deepening its business ties with China, describing closer economic engagement with Beijing as “dangerous,” even as UK Prime Minister Keir Starmer praised the benefits of resetting relations during his official visit to China.

Speaking to reporters, President Trump said closer cooperation with China posed strategic and economic risks, urging the UK to remain cautious in its dealings with Beijing. His remarks underscore growing concern in Washington over China’s global influence and the implications for Western allies.

Prime Minister Starmer, however, struck a more optimistic tone in Beijing, highlighting what he described as tangible progress in revitalising UK-China relations. He said renewed engagement would unlock economic opportunities for British businesses, boost trade and investment, and support long-term growth at a time of global economic uncertainty.

Starmer emphasized that Britain’s approach toward China would be pragmatic and “sophisticated,” balancing national security considerations with the need for constructive dialogue and economic cooperation. Discussions during the visit focused on trade, technology, green energy and expanding market access for UK firms.

The contrasting messages from Washington and London highlight differing approaches among Western allies toward China, as governments navigate the complex challenge of safeguarding national interests while maintaining economic ties with the world’s second-largest economy.
