The Estrada Doctrine (also known as La Doctrina Mexico, La Doctrina Mexicana and La Doctrina Ortiz Rubio) is Mexico's core foreign policy guideline since 1930; according to it, states should not formally announce the diplomatic recognition of foreign governments, as that could be perceived as a judgment on the legitimacy of said government, and such an action would imply a breach of state sovereignty.[1] The policy is based on the principles of non-intervention, peaceful resolution of disputes and self-determination of all nations.[2] In line with the Estrada doctrine, Mexico to this day – and in contrast with most other states – does not issue formal declarations of diplomatic recognition of new states or governments.[3]
The doctrine’s name derives from Genaro Estrada, Secretary of Foreign Affairs during the presidency of Pascual Ortiz Rubio (1930–1932).[1][4]
