In 1956 Dwight D. Eisenhower established the "Sister Cities Program" to promote greater understanding and peace among citizens throughout the world. Tucson embraced this vision and has adopted formal relations with communities in Hungary, Kazakhstan, Spain, Ireland, Greece and Mexico.
The Tucson-Mexico Sister Cities Committee has enjoyed a very special relationship with Guadalajara, Jalisco since 1972, Ciudad Obregón, Sonora since 1980 and now Mazatlan, Sinaloa and Puerto Peñasco, Sonora.
"Increased collaboration with our friends in Mexico presents outstanding opportunities for our cities. Our shared interests are the foundation of our strong relationship."
- Mayor Bob Walkup, City Of Tucson
