Sister Cities International (SCI) is the world’s oldest and largest volunteer network of citizen diplomats. Since our inception in 1956, SCI has worked to promote peace and mutual understanding through global partnerships based on culture, education, and economic exchanges.
Our Global Leaders Circle (GLC) is a thriving network of individuals, businesses, and organizations that have publicly demonstrated their support for global peace and prosperity. Your generous gift to Sister Cities International not only supports our work to promote peace through mutual respect, understanding, and cooperation – one individual, one community at a time, but also gives you the opportunity to align with a powerful, thriving global and local network of those most committed to our mission.
