The United States and the United Kingdom have failed to sign an international agreement on artificial intelligence (AI) at a global summit being held in Paris.
The declaration, signed by France, China and India among other countries, promises an "open", "inclusive" and "ethical" approach to technology development, the BBC reports.
The British government has said that the UK "has not been able to agree on all parts of the leaders' statement" and that it "will only sign up to initiatives that are in the UK's national interests".
US Vice President JD Vance has told delegates in Paris that excessive regulation of artificial intelligence (AI) could kill the transformative industry.
Vance told world leaders that AI is an opportunity that the Trump administration will not squander, adding that pro-AI growth policies must take priority over security.
His comments have put him at odds with French President Emmanuel Macron, who has advocated the need for further regulation.
"We need these rules for AI to move forward," Macron said at the summit.
The UK has previously championed the idea of AI safety, with then-Prime Minister Rishi Sunak holding the world's first AI Safety Summit in November 2023.
Andrew Dudfield, head of AI at fact-checking organisation Full Fact, said the government's decision not to sign the Paris communique put it at risk.
"By refusing to sign up to today's international AI action declaration, the UK government risks undermining its hard-earned credibility as a world leader for safe, ethical and trustworthy AI innovation," he said.
