Except that's wrong because no one is claiming it belongs to anyone but Taiwan because it does belong to Taiwan. Canada isn't doing this because they think they own the waters, they're doing it because they're allies of Taiwan and they're just defending their allies from being attacked by China

Canada is actually allied with countries on the other side of the planet. China isn't allied with anyone but Russia because no one wants China anywhere near them

They constantly try to divert attention away from serious disasters happening within their own borders.
