According to information from the area of International and National Promotion of the Federal Authority for the Development of Special Economic Zones, to date almost 90 companies have letters of intent to invest in the seven decreed zones of the country.

The director of the area, Juan Carlos Cardona, said that the goal is that by the end of 2018 there will be a private administrator for each of the Special Economic Zones (ZEE).

During the first stage of the Special Economic Zones project, the seven Special Economic Zones (SEZs) were defined as: Puerto Chiapas, Coatzacoalcos, Lázaro Cárdenas - La Unión, Salina Cruz, Progreso, Tabasco and Campeche. This project was created to promote the economic development of the south - southeast states of the country.
