Earlier the Bengal Communists used to be strongly pro-China and hundreds of them were even imprisoned in 1962. The Kerala Commies including EMS were nationalists and supported India in the war. The CCP (Chinese Communist Party) even criticised the CPI for forming the first Government in Kerala after the 1957 elections at the international meeting of communist parties in Moscow.
Looks like the Kerala Commies are now leading Bengal in terms of being pro-china and the nationalists have disappeared. Way to go...!
