Wang Ming
In July 1931, Wang Ming removed himself to Moscow and assumed the position of chief Chinese representative on the Comintern. Kang and his wife Cao Yi'ou followed two years later. Kang remained in Moscow for four years, acting as Wang's deputy on the Comintern, returning to China in 1937. While in Moscow, Kang was elected a member of the Politburo of the CPC, perhaps as early as 1931 but more probably in January 1934.
