This special issue of the Revista Mexicana de Política Exterior promotes reflection on the position that Mexico occupies in international relations at the beginning of the 21st century. To this end, 17 specialists from the Foreign Ministry were invited to share their ideas about the achievements and challenges of the government of President Ernesto Zedillo Ponce de León (1994-2000) in terms of foreign policy. In their capacity as co-participants of Mexican foreign policy in that period, nobody better to explain the objectives and the challenges faced and, perhaps also, to evaluate the pending subjects. In any case, the ideas of the officials gathered here are indispensable in the debate on Mexico's foreign policy in the period 1994-2000.
