The charges were from the state of New York, not federal, and Meng Wanzhou had been being investigated since the Obama administration. The idea that Canada was just a patsy of the USA was literally the Chinese propaganda line for all this and it was really shitty as a Canadian to be thrown under the bus by Americans repeating that line just so they could try and dunk on Trump.

And China themselves didn't even really believe it, otherwise they wouldn't have gone after Canadians in China as their revenge.
