The article is devoted to the comparative analysis of the concept, types and forms of Eurasian and Latin-American integration associations. On the authors’ mind the integration association is the group of states united on the basis of an international treaty to achieve the integration goals. It is proposed to distinguish between the integration associations of the coordination and supranational types. According to the identified features of each of the indicated types of integration associations the authors conclude that the Organization of American States is the union of the coordination type, the MERCOSUR is in transition from coordination to supranational integration association, in the Andean Community the supranational model is implemented, and the Eurasian Economic Union tends to the supranational association. It is noted that integration associations can be also classified depending on the different forms of economic integration (free trade area, customs union, common market, economic union, etc.). The main forms of the Latin-American economic integration are free trade area and customs union, while the common market is still developing. The forms of the Eurasian economic integration are the customs union, the common economic space, forming common market. A trend of formation of new forms and types of inter-state integration associations and cooperation between them, particularly in the form of a mega-association (Union of South American Nations) is revealed. The ways of further development of the integration associations in Latin America and Eurasia are marked.
