In early 1927, the NPA Political Commission, in an effort to make Zhang Zuolin seem more legitimate and popular, declared that a new policy would be taken by Zhang: "Development of the democratic spirit and opposition to oppression by force. Restoration of the national sovereignty and abolition of the "unequal treaties." Improvement of economic conditions and co-operation between capital and labor. Encouragement of popular education. Enforcement of a system of local self government. Reclamation of the frontiers and colonization of undeveloped areas. Preservation of the national sovereignty and characteristics. Readjustment of official morality and development of the morality of the people."
