Mission and History

To promote peace through mutual respect, understanding, and cooperation — one individual, one community at a time.

Sister Cities International was created at President
Eisenhower’s 1956 White House conference on citizen diplomacy. Eisenhower envisioned an organization that could be the hub of peace and prosperity by creating bonds between people from different cities around the world. By forming these relationships, President Eisenhower reasoned that people of different cultures could celebrate and appreciate their differences and build partnerships that would lessen the chance of new conflicts.

Sister Cities International creates relationships based on cultural, educational, information and trade exchanges, creating lifelong friendships that provide prosperity and peace through person-to-person “citizen diplomacy.” Since then, Presidents Kennedy, Johnson, Nixon, Ford, Carter, Reagan, Bush, Clinton, Bush, and now President Barack Obama have served as the Honorary Chairman of Sister Cities International.

Since its inception, Sister Cities International has played a key role in renewing and strengthening important global relationships. Early partnerships included a trading relationship between Seattle, Washington and Tokyo, Japan, repairing post-WWII tensions by creating cultural and educational exchanges and, subsequently, lasting friendships. A 1974 study found that many early sister city relationships formed out of the post WWII aid programs to Western Europe. The relationships that endured, however, were based on cultural or educational reasons that developed lasting friendships. Sister Cities International improved diplomatic relationships at watershed moments over the past 50 years, including partnerships with China in the 1970s.

In the new millennium, Sister Cities International continues to expand its reach to new and emerging regions of the world. Today, it dedicates a special focus on areas with significant opportunities for cultural and educational exchanges, economic partnerships, and humanitarian assistance.
