The A-B Group, established in Nanchang, Jiangxi Province towards the end of 1926, was an organization of the Kuomintang right wing as opposed to the CPC. It was destroyed by the revolutionary masses in April 1927. In the first half of 1930 the Southwestern Jiangxi Revolutionary Base Area was first to wage the struggle against the so-called A-B Group by eliminating counter-revolutionaries. After 1931, the struggle spread to the Hubei-Henan-Anhui Revolutionary Base Area and the Western Hunan-Hubei Revolutionary Base Area. The struggle against the A-B Group obscured the contradictions between ourselves and the enemy, enlarged the scope of suppression of the counter-revolutionaries, and caused serious consequences.
