City Connection Marketplace

Cities Seeking Cities Banner

Our City Connection Marketplace program is available to members to provide hands-on assistance in establishing new sister city, county, or state partnerships. We help dozens of cities start the partnership process from scratch and assist many more at various stages of their search.

Whether it’s your first partnership or your tenth, Sister Cities International staff is available to assist and guide you through the process from researching potential partner cities, to crafting and signing and agreement.

Thanks to our connections to foreign Embassies in Washington, D.C. and relationships with U.S. Foreign Service Officers around the globe, Sister Cities International is uniquely positioned to help you get in touch with decision-makers abroad.

Concord might never have paired with Freeport, Bahamas had it not been for the assistance of the Cities Seeking Cities program. Concord Sister Cities Association is most grateful for the help and the guidance and will most certainly turn to SCI again when looking for another sister city in the future!

– John Dunlap, President of the Concord Sister Cities Association
