American states are ramping up regulations on China with over 240 proposed measures aimed at restricting Chinese technology and goods to mitigate concerns around cybersecurity and infrastructure vulnerabilities. The move underscores the escalating tensions between the US and China, with some viewing China as a potential threat. These measures encompass various aspects such as investments, contracts, and even sister-city relationships, as states strive to limit Chinese influence within their jurisdictions. The tightening rules reflect a broader trend of increasing scrutiny on Chinese activities in the US.
