The opposite could also be argued. Most AI safety training today is to ensure compliance with various forms of ethics and ideologies. This is known to reduce general intelligence, but some companies feel the cost is worth it and others do not (e.g. Mistral, Grok AI).
China is not exactly an ideology free society. The list of things you cannot say in China without angering the government is very large. This is especially difficult for an AI training company to handle because so much of the rules are implied and unstated, based on reading the tea leaves of the latest speeches by officials. Naively, you would expect a Chinese chatbot to be very heavily RLHF conditioned and to require continuous ongoing retraining to avoid saying anything that contradicts the state ideology.
Such efforts may also face difficulties getting enough training material. IIRC getting permission to crawl the English-speaking internet is very difficult in China, and if you don't have special access then you just won't be able to get reliable bandwidth across the border routers.
