With this issue a new stage of the Revista Mexicana de Política Exterior begins, which throughout its 33 issues has become a multidisciplinary forum in which the various approaches of specialists in foreign policy are reproduced. At IMRED we hope to fill a space conducive to reflection that stimulates the reader to research and analyze the international context. On this occasion the topics discussed are: the meeting of two worlds; the concept of sovereignty; the recognition of the States, and the migratory movements in the world.
