Country Representatives

Country Representatives play a vital role in advancing Sister Cities International (SCI) by serving as a key liaison between their country and the broader SCI network. Internationally, they advocate for SCI’s mission, acting as an extension of the Board Chair and President and CEO, while fostering new and existing partnerships with U.S. cities. They work to establish and strengthen municipal, civic, and professional alliances that enhance SCI’s global presence. Domestically, they lead their country’s outreach to the SCI member network by forming a country committee of U.S. cities and organizing at least two roundtables annually. Additionally, they actively engage with State Representatives and local programs to promote international collaboration, expand partnerships, and increase the number of U.S. dues-paying member cities, ensuring sustained and meaningful global connections.
