Amid the confusion, some Chinese AI companies have taken the opportunity to woo disgruntled users

An abrupt decision by American artificial intelligence firm Anthropic to restrict service to Chinese-owned entities anywhere in the world has cast uncertainty over some Claude-dependent overseas tools backed by China’s tech giants.

After Anthropic’s notice on Friday that it would upgrade access restrictions to entities “more than 50 per cent owned … by companies headquartered in unsupported regions” such as China, regardless of where they are, Chinese users have fretted over whether they could still access the San Francisco-based firm’s industry-leading AI models.

While it remains unknown how many entities could be affected and how the restrictions would be implemented, anxiety has started to spread among some users.

Singapore-based Trae, an AI-powered code editor launched by Chinese tech giant ByteDance for overseas users, is a known user of OpenAI’s GPT and Anthropic’s Claude models. A number of users of Trae have raised the issue of refunds to Trae staff on developer platforms over concerns that their access to Claude would no longer be available.
