Estrada Doctrine
The Estrada Doctrine is the name of Mexico's core foreign policy ideal from 1930 to the early 2000s. Its name derives from Genaro Estrada, Secretary of Foreign Affairs during the presidency of Pascual Ortiz Rubio (1930–1932).
The doctrine was the most influential and representative instrument in the country's foreign policy for seventy years, it claims that foreign governments should not judge, positively or negatively, the governments or changes in government of other states, in that such action would imply a breach of state sovereignty. This policy was said to be based on the principles of non-intervention, peaceful resolution of disputes and self-determination of all nations.
