The CCP’s 9 December 1941 declaration called for the formation of an anti-Japanese and anti-fascist front in the Pacific that would include all the governments and peoples who were opposing Japan. Now the USA and Great Britain were seen as having an important role to play in defeating Japan and bringing about unity in China. "Left" deviation was to be avoided and all party members were to cooperate with the British and Americans.
The dissolution of the Comintern (15 May 1943) freed the CCP from any need to bow in its direction and re-affirmed what was already a reality for Mao and his supporters that the CCP should get on with creating its own revolution on its own terms. Also, it undercut any last possible support base for Wang Ming and his followers. Combined with other internal factors, it contributed to the build up of a cult around Mao Zedong.
On 26 May, after the CCP had received the information, the Politburo met to discuss the issue and in the name of the CC issued a decision on the matter. Not surprisingly, the decision wholly agreed with the Comintern’s abolition pointing out that this would strengthen the local communist parties by making them "even more nationalized." Such a leading center was no longer considered necessary and, interestingly, the decision points out that the Comintern had not interfered in CCP affairs since 1935. The need to assert the continued and strengthened role the CCP would play without the Comintern was further necessitated by the calls by some CCP domestic critics that it could now disband.
There is an abundance of sources for the study of the CCP during the years from 1919 until 1943 but still many areas of the relationship remain murky. Some of the outstanding questions may be resolved by the opening of the archives in Moscow and research that is now in progress.
Extensive collections of materials concerning the Chinese revolution are held in Moscow, especially in the Comintern Archives at the Russian Center for the Storing and Study of Documents of Contemporary History (formerly the Central Party Archives).
1) The Central Archives (Zhongyang dang’an), Wen Quan Village, Beijing. These archives comprise the main holdings of the CCP. Among other material, it contains archives and related documents since the founding of the CCP from the CC and its affiliated organizations, their agencies, as well as from revolutionary groups and front organizations from different periods. There are 202 complete files with approximately 8 million pieces. Among the materials is the archive of the CCP delegation to the Comintern. This contains important documents of the Comintern, and resolutions, decisions, announcements on China by the ECCI, the Far East Bureau, and the Eastern Department, as well as by the Youth Communist International and the Workers’ International. Alas, entrance is highly restricted even for Chinese researchers and virtually impossible for foreigners. It is important to note that there are relevant archives held at all administrative levels in China that are relevant to the history of the CCP.
