The UFWD was used in the early years of communist rule "to guarantee CCP oversight" over groups that were not directly associated with the Party and government. Those groups, including NGOs, were brought under the authority of the UFWD, whose job it was to “continuing to play its part in mobilizing and rallying the whole people in common struggle” after the Liberation in 1949. When the CCP "shifted its focus from the 'mass line' to 'class struggle', the real united front disappeared. While the United Front Department still existed, its duties of uniting with all forces for the 'common struggle' shifted mainly to serving the Party's leadership and 'consolidating the proletarian dictatorship'," according to Brookings Institution visiting fellow Zhang Ye. Based on their actions in Taiwan and elsewhere the United Front Work Department appears to be used as a cover to conduct intelligence operations against targets of interest to the CCP.
