Latin American countries have greatly enhanced their diplomatic independence and autonomy by implementing diversified diplomatic strategies with more emphasis on economic affairs. There is a complex diversity of integration in this region，but progress has been slow. Small Latin American countries and the Pope have played a positive role in mediating regional affairs. The focus of the US policy has been to promote the normalization of relations with Cuba，support the peace talk in Columbia and strengthen the relationship with the Pacific Alliance. Despite declining clout in the region，the European Union and some Western European powers try to keep their influence in Latin America through intervention and participation. The geo-economic diversification of this region has been particularly inclined to the Asia Pacific region，and China has become an important strategic cooperation partner. In multilateral areas，Latin American countries have played an increasingly important role in the reform of the UN Security Council，global development agenda，climate change and other issues of global governance，but it is difficult to coordinate the positions in the region.
