Founded by President Dwight D. Eisenhower in 1956, Sister Cities International is a 501(c)(3) nonpartisan nonprofit serving as the national membership organization for individual sister cities, counties, and states across the United States. This network unites tens of thousands of citizen diplomats and volunteers in programs in 140 countries on six continents. Sister Cities International advances peace and prosperity through cultural, educational, humanitarian, and economic development exchanges. It serves as a hub for institutional knowledge and best practices in the field of citizen diplomacy.

Citizen Diplomacy Initiatives promotes trilateral sister city programs around the world, such as the Gainesville, Fl / Qalqilya, Palestine / Kfar Saba program.
Through these three way sister cities, relationships are built across nations that lead to positive change within the involved communities.

EcoPeace Middle East is a unique organization that brings together Jordanian, Palestinian, and Israeli environmentalists. Our primary objective is the promotion of
cooperative efforts to protect our shared environmental heritage. In so doing, we seek to advance both sustainable regional development and the creation of necessary conditions for lasting peace in
our region. EcoPeace has offices in Amman, Bethlehem, and Tel-Aviv.
