The National League of Cities (NLC), the nation’s largest membership and advocacy organization for local elected officials, and Sister Cities International, a nonprofit focused on creating global relationships have agreed to a new partnership that will improve relations and networking between the two organizations and enhance benefits for their respective members. 

“The National League of Cities is proud to formalize our partnership with Sister Cities International,” said Clarence E. Anthony, CEO and executive director of the NLC.  “This partnership represents an important step in our shared commitment to building stronger, more prosperous communities. We look forward to the important work that lies ahead.”

NLC and SCI have a shared history. NLC has served U.S. cities, towns, villages and state municipal leagues since 1924. SCI’s origins date back to the 1956 White House Summit on Citizen Diplomacy.  While the NLC, then the American Municipal Association, approved participation in a joint cooperative program with the Civic Committee of People-to-People to further the U.S. Sister Cities program on July 24, 1957. Both organizations are committed to sustained community-to-community connection.

“This is a significant moment in the history for our country, to have two of the biggest city membership organizations come together to build a stronger and more prosperous America,” said Roger Mark De Souza, president and CEO of Sister Cities International.  “We will be connecting on another level with the rest of the world to improve partnerships and communication between global communities.”


The National League of Cities (NLC) is the voice of America’s cities, towns and villages, representing more than 200 million people across the country.
