Why not - the Chinese have already ‘reconsidered’ who owns Tibet, and they’re ‘reconsidering’ who owns Taiwan and India.
Japan, you’re next; not just Okinawa, but the four main islands, too - Kyushu, Shikoku, Honshu, and Hokkaido.
Then, no doubt, Hawaii and maybe California.
Pissing off the Japanese, Vietnamese. Taiwanese and Indians all at the same time, not to mention the USA might not be in Chinas' best interest. I'm also pretty sure Russia is keeping an eye on China too.
I think they can have California, at least everything south from Sacramento south. From Redding north it is like a different state anyway.
