Anthropic doesn't allow Claude in China and neither does OpenAI. But the rest of Asia certainly has a choice. Unless you mean socioeconomically. Also there's plenty of loopholes people in China can use to still access those models
If you buy Claude api access through a third party Chinese company, it's cheaper than when you buy directly.
Beside it would go against the Chinese philosophy of just using the right tool for the job. If Claude is better at a task than deepseek, they sure use Claude.
No really I don't get your claim, do you have any proof that you can source ??
