The mayors of Phoenix and Tucson lead a trade mission to Mexico this week as part of effort to foster relations with Arizona’s largest trading partner.

Phoenix’s Greg Stanton and Tucson’s Jonathan Rothschild will be joined by Phoenix City Councilman Michael Nowakowski, Phoenix City Manager David Cavazos, representatives from the Greater Phoenix Economic Council and various Arizona chambers of commerce.

The group will travel to Hermosillo to meet with Sonora Gov. Guillermo Padres Elias and others and then tour a manufacturing facility.

They later will head to Mexico City to meet with representatives from the Mexico Secretary of Tourism, Aeromexico, U.S. Ambassador and Mexico Secretary of Foreign Affairs and others.

Cavazos says Mexico is Arizona’s largest trading partner with the state exporting $5.7 billion in merchandise to Mexico last year.
