Ummm… In China, prohibited or heavily restricted areas of research include democracy, human rights, Tibet, Xinjiang, Taiwan, Tiananmen, criticism of the Communist Party, censorship circumvention tools, human reproductive cloning, genetic modification of human embryos for reproduction, stem cell work beyond 14 days of embryo development, unapproved clinical stem cell applications, organ transplantation outside regulated systems, unauthorized cryptography, dual-use or national-security technologies, nuclear technology, unrestricted sharing of genomic or health data, foreign collaboration on sensitive datasets, and archaeological or historical research that challenges official state narratives.

You are actually stupid if you think scientists will have more freedom in China than the US.
