A sister city relationship is one formed between two cities in different countries. The idea was first introduced by President Eisenhower in 1956, who promoted links between citizens of different countries in an effort to bring about citizen diplomacy and build global cooperation at a local level. Cities can have more than one sister city; Chicago is currently leading the pack with 28 sister cities, followed by Los Angeles with 25. A sister city is officially recognized once the highest elected official from both cities sign off on an agreement. What are the objectives of sister city relationships?

Sister city relationships are meant to be mutually beneficial and may address several different aspects of community development. For example, sister city relationships have helped cities implement innovative policies and management techniques in sanitation, water, health, transportation, tourism, economic development and education. Sister city partnerships may also help each other during natural disasters or other emergencies by raising funds or collecting needed-supplies. Sister cities may also support schools and clinics through donation of materials or skills-training. With regard to business and trade, sister city programs create connections with international municipal officials, institutions and businesses. These connections build trust, access, and expertise that help local businesses find new opportunities such as access to new markets, assistance navigating import/export regulations, and expanding availability of resources. Arts and culture exchanges are some of the oldest international partnerships around. By sharing each other’s cultures through sister city relationships, communities can gain insight into the history, values and spirit that make up their sister city. Exchanges may take different forms including musical performances, art exhibits, peace parks and gardens, and international cultural festivals. Opportunities for international and diplomacy experience for youth is also a benefit of sister city relationships. They provide a unique opportunity for youth to travel abroad and experience another community as a guest, rather than a tourist. Activities often include short- and long-term student exchanges and sports tournaments.
