I see where you are coming from, that kind of chest thumping angle only plays into the "China threat" and the perception of perennial tensions between China and the rest of the world, especially when paired with the existing underlying mistrust where the likely superficial interpretation (encouraged by those wanting to demonize China) would be: "Look, so much of the world was united against China even back then! It must be wrong/evil by nature!"
My point is that map requires too much context to interpret accurately and when used simplistically tends to lend its weight to mischaracterizing China rather than not.
Fair enough though Australia would be the exception rather than the rule among most colonies/invaded/occupied countries/peoples.
Yes no doubt that's the intend to make it look like the whole world is against China. But it doesn't change the facts that these dominions were under the control of the 8 nations empires!
