I mean if you’re conflating invading and annexing parts of or whole independent nations with the naming of bodies of water and other geographic features, I can’t help you with that one. You’ll need a professional. That’s not even half the gotcha you think it is.
I’m not even one to defend the PRC, but between the PRC, the Republic of China, Korea, Japan, and Russia there’s a lot of land and naming disputes between them.
