Very similar to the situation of leftism in India.
The CPI was openly anti-China - although they’re open to merging back with the CPIM. But the CPI isn’t as relevant as the CPIM. The CPIM, which was carved out of CPI, had a split, owing to the Sino-Soviet split. And then the communist parties in India kept fragmenting over minute ideological differences - some into Marxist-Leninists, Trotskyist, Maoists, etc , and some went out of relevance. None of these parties, however, have any connection to the HSRA, aka the original anti-colonialist revolutionaries. Now, there are fake (non-Marxist), wannabe socialist/communist (read: welfare capitalist) parties like the INC and SP with considerable seats in the Indian parliament.
In the case of JCP, they seems to all with the Soviets strongly, just like old-timers at CPI.
