White House's ban on foreign access to Anthropic's AI model dominates G7 talks, sparking concerns among US allies about technological dependence.

What happened: The White House blocked foreigners from accessing Anthropic's cutting-edge AI model. The move triggered immediate alarm at a G7 summit opening in France, with the EU citing a need for 'technological sovereignty' and Canada's leader warning of risks from relying on a small cluster of powerful US tech firms.

Why it matters: Western middle powers have largely trailed the US and China in the AI race. France's leading AI firm, Mistral, is in talks to raise funding at a valuation of about $23 billion（約3.7兆円） — roughly 40 times smaller than Anthropic's estimated valuation — highlighting how far behind allied nations lag in building competitive AI capacity.

What to watch: The decision is poised to be a dominant topic at the G7 summit, signaling potential fractures among Western allies over AI access and control of advanced technology.
