not sure about all chinese models, but deepseek has absolutely no problem and qwen just avoids anything controvertial including completely unrelated subjects to china such as the lgbtq movement. also any kind of safeguards like those are easily bypassed since there isn't that much effort that was put in to prevent models talking about these subjects which to be sounds like dataset tainting rather than intentional bias.

I just tested this with Deepseek in Nvidia's AI sandbox and in Groq (so the inference was performed in the US) and it happily told me what happened on June 4, 1989. Stop spreading disinformation.
