Mexican President Peña Nieto made substantial progress in structural reform in 2015，and public security has become one of the main targets of government policy. The president also needs to struggle to recover credibility amid social frustration over institutional deficiencies，notable corruption and violence. The party system is fragmented. In the face of adversities in the international environment，especially the impact of low oil prices，the main goal of Mexico’s economic policy is to ensure the stability of the macro economy. Public security and corruption remain great challenges to social development，and the government has failed to reduce poverty levels. On the diplomatic front，Mexico is developing relations with countries of North America，Latin America and Asia Pacific.
