You do have somewhat of a point here. The US is one of only two countries (and the only country that can make it stick) that sees any American or any person born in the US, as falling under US tax law, and requires them to file taxes in the US, even if they don't live there or work there. Banks across the world are required to enforce this and have special rules for "US Persons" or they're not allowed to do business with the US, which is understandably crippling for any bank. Because of this, even some people who feel like they have no connection with the US at all, may be unable to open a bank account anywhere unless they agree to file taxes in the US. So yes, the US also tries to exert power over people it considers American subjects well outside its jurisdiction. That doesn't excuse China intimidating and threatening Chinese people living abroad, though.
