The formation of the party was announced in early September 1964, with Youssef Moubarek as party chairman and Moustafa Chaker as general secretary.[1][2] The group published Ila amam ('Forward'). The group did not fully support the line of Mao Zedong, but notably did not support the Soviet Union in their dispute with China. The group argued that the mainstream of the Lebanese Communist Party had become too supportive of Nasser, and accused Khalid Bakdash of 'revisionism'.
