Can you explain what you mean? The USA never had “lockdowns” at all – to some degree because of public pressure though also because for the first year or so of the crisis the federal government flailed around passively/counterproductively due to abject incompetence (plus some grifting) at the top. Meanwhile China’s Covid policy had nothing whatsoever to do with the American electorate or stakeholders, but was instead driven by political pressures internal to China.
If your point is that different American states responded differently despite broadly similar public opinion based on party affiliation of the legislators and governors, that’s true, and part of how our the US system works. Public preferences clearly aren’t the only thing driving policy decisions.
