Harvard professor Charles Lieber had similar allegations, and he's not ethnically Chinese. There's millions of ethnic Chinese in Taiwan, Malaysia and elsewhere who are against Communist China. I agree the CCP has a strong 'ethnonationalist' ideology that tries to go beyond nationality. This needs to be strongly pushed back upon, but banning all ethnic Chinese is not the answer. Please keep in mind the centuries of historical context with anti-Asian immigration sentiment ("Yellow Peril"). I agree given the risks the world should put great thought into limiting (even banning) all immigration from the PRC because the security risks are too great. But that law should not apply to Taiwan, Malaysia etc if the people immigrating have proven themselves anti-CCP.
