The Matías Romero Institute is proud to make available to readers the 100th installment of the Revista Mexicana de Política Exterior after being founded a little over thirty years ago and directed by outstanding diplomats and internationalists, the RMPE has established itself as a space for public deliberation on foreign policy and international relations. As can be seen, its editorial design has also been transformed and its content will henceforth be accompanied by the standards that distinguish specialized magazines. We hope that this new design will be to the liking of our readers.
