The foreign relations of Mexico are directed by the President of Mexico and managed through the Ministry of Foreign Affairs. The principles of the foreign policy are constitutionally recognized in the Article 89, Section 10, which include: respect for international law and legal equality of states, their sovereignty and independence, trend to non-interventionism in the domestic affairs of other countries, peaceful resolution of conflicts, and promotion of collective security through active participation in international organizations. Since the 1930s, the Estrada Doctrine has served as a crucial complement to these principles.
