In 1923, a joint statement by Sun and Soviet representative Adolph Joffe in Shanghai pledged Soviet assistance to China's unification. The Sun-Joffe Manifesto was a declaration of cooperation among the Comintern, KMT and CPC. Comintern agent Mikhail Borodin arrived in China in 1923 to aid in the reorganization and consolidation of the KMT along the lines of the Communist Party of the Soviet Union. The CPC joined the KMT to form the First United Front.
