Iirc, China used to support Japan and the JCP until the early 1980's. Mostly bc of the Soviet-Sino split and bc of Japan's economy. I guess there was a small period where China, Japan and the Koreas could have created their own economic bloc. But that quickly ended, the USSR ended the split in 1988 with Gorbachev visiting China, and Japan's economy got fucked.
