[1] Suárez had made his fortune in various infrastructure projects including water supply systems, canals and railways, and in sugar mills that were later nationalized.

[2] He conceived the idea of building a major business and tourist complex named Mexico 2000, centered around the huge Hotel de México.

Rossell presented the project to Franco-Mexican diplomats at the Grand Palais in Paris, accompanied by Siqueros and the Minister of Tourism Miguel Alemán Valdés.

He claimed it would act as a vehicle for reconciliation of postwar ethnic, linguistic and geopolitical differences, and would help reunite the physical and social urban fabric of Mexico city.

[10] As delays continued there was growing tension between Suárez and the elite of the PRI, which disputed claims that the hotel could symbolize the enlightened sovereignty of the state, resolving social, urban and political problems and refused to authorize discounted loans to complete the project.

[14] The Grupo Gusto bought the shell of the building to convert it into the World Trade Centre Mexico City, an office space, inaugurated by President Carlos Salinas on 19 November 1994.

[12] At the start of the 1990s the office of Gutiérrez Cortina Arquitectos was commissioned to redesign and convert the building into the World Trade Centre México.

[3][6] In July 2005 the World Trade Center was sold at auction for $58 million by the government's Fondo Bancario de Protección al Ahorro (Fobaproa).

[17] The architects Rossell and Ramón Miquela Jáuregui worked with Siqueros to design a diamond-shaped building that would present a huge surface for his mural.

It was built by the architects Guillermo Rossell de la Lama, Ramón Miquela Jáuregui and Joaquín Álvarez Ordonéz.

[3] The Polyforum mural of the "March of Humanity" by Siqueros acknowledges the potential of technological progress but is critical of the failure of the Mexican Revolution to achieve freedom and social justice.
