Does the fact that China owns nuclear weapon improve the status of Chinese expat?

According to Chinese government propaganda, it is because of the development and deployment of nuclear weapons that the status of Chinese ex-pats is no longer discriminated against by anyone else. Are there any documents or research that can prove that there is a direct link between the increasing military might of the PRC and the fact there are fewer anti-Chinese riots and discriminatory acts against a Chinese in western bloc nations (US, Canada, Europe in particular) between mid-1960s to 1990s
