The purpose of the article is to identify the foundations of China’s integration policy and the features of its integration agreements with developing countries, i.e. in the framework of the South- South model. The basis of the Chinese integration strategy is the principle of “big country morality”, which allows to assist developing countries with small territory and to a lesser extent proceed from accounting for the economic advantages of membership in an agreement (no wonder some agreements have the effect of deviating trade for the PRC). The developing countries are China's main partners in the integration agreements (12 out of 16). The article compares the norms of China's integration agreements with individual partner countries, and examines the impact of membership on Chinese foreign trade relations and identifies the most effective agreements. The main conclusions of the authors include the prevalence of the South-South model as bilateral agreements, the liberalization of trade in goods and services, the priority in signing agreements with the countries of Asia; relatively narrow scope and rarely include issues of protection of intellectual property rights, competition policy, ecology, public procurement; application of a flexible approach to the selection of partners for integration agreements and the content of agreements; more dynamic growth of China’s exports to partner countries on integration agreements; Integration agreements with ASEAN, the Republic of Korea and Pakistan became the most effective for the PRC.
