The thing is that it will never happen. China is still increasing its economic lead over US quickly, and Japan isn't even in that race.I still think it's more useful to focus on bringing neutral countries into the positive than to bring hostile countries into the neutral. For example bringing Vietnam into the positive in 2024.
Japan is likely doing this because their GDP is falling like a rock. At any time that they perceive they have an advantage they'll likely become hostile again.
If what you and some other say is correct (that Japan will stay friendly until the moment they feel the winds turn in favor of US/themselves), then the Japan problem is actually solved, because there is nothing that projects a potential change in power relations like that.I don't think that China should be unreasonably hostile to Japan but the problem lies with Japan.
