The paper examines the problem of global integration processes in regions of Africa, Asia and Russia. Based on migration flows, estimation of integration indexes, we investigate the historical integration development of these regions and identify the important features for future international cooperation and integration. This article presents the preliminary results of the gravity model that we constructed using the features of Asia-Pacific region. We concluded that differences and similarities in sectoral structure of GDP do not influence increasing of mutual trade between countries and its partners. It evaluates the potential benefits for Asia-Pacific region by expanding the market for export industries worldwide.
