瞿秋白
In July 1927 the Comintern sent him to China to urge the Chinese Communist Party to adopt a more militant policy and find a Kuomintang element willing to allow a Communist Party fraction to operate within the KMT. He engineered the removal of Chen Duxiu, the founding head of the Chinese Communist Party, who was made the scapegoat for the failed policy of trying to infiltrate and take over the Kuomintang from within, and picked as the younger and less experienced Qu Qiubai as his replacement, before the August 7 Emergency conference at which many former leaders were expelled "in order to secure a new CCP leadership that would embrace Stalin's policies." At that session, over which Lominadze presided, Mao Zedong was promoted to alternate membership of the Politburo.
