Seven weeks from today, the Sister Cities International network will come together in Washington, DC for a once-in-a-generation celebration.
From July 22–25, the 70th Anniversary Homecoming will bring together local leaders, citizen diplomats, young professionals, international partners, and friends from across Sister Cities programs to celebrate seven decades of building global connections.
This is more than a conference. It's a chance to reconnect with colleagues from around the world, hear from leaders shaping the future of citizen diplomacy, visit embassies, explore new partnerships, and be part of a milestone moment in Sister Cities International history.
Join us for regional briefings, panels, showcases, awards, special events, networking opportunities, and more as we celebrate 70 years of impact and look ahead to the next chapter.
