Whataboutism. Canada has little to fear from US hegemony and a lot to fear from Chinese hegemony, it's as simple as that.
Simple fact is that there's no Chinese hegemony now and there won't be one in foreseeable future because there's existing hegemon that won't just give up.
btw one man's whataboutism is another man's uncovering of hypocrisy.
They didn't say anything about the USA hegemony being bad just that they didn't want a Chinese one. How is that hypocrisy?
