Join Sister Cities of the Tri-Cities
What is Sister Cities?

A national sister city movement emerged when President Dwight D. Eisenhower convened a White House conference in 1956 on citizen  diplomacy. From this eventually grew the Sister Cities International organization. Sister Cities is a nonprofit citizen diplomacy network designed to create and strengthen partnerships between the United States and international communities, in order to:

  • increase global cooperation at the municipal level
  • promote cultural understanding
  • stimulate economic development
