San Diego Sister Cities

Taking San Diego to the World, Bringing the World to San Diego.

Sister Cities International was created at President Eisenhower’s 1956 White House summit on citizen diplomacy, where he envisioned a network that would be a champion for peace and prosperity by fostering bonds between people from different communities around the world. President Eisenhower reasoned that people from different cultures could understand, appreciate, and celebrate their differences while building partnerships that would lessen the chance of new conflicts.

Formed in 1993, SanDISCA was created as an umbrella organization for all Sixteen Sister City Societies of San Diego. SanDISCA works to maintain citizen–diplomat relations with each sister city while each individual sister society has its own membership, pursues its own mission and conducts its own cultural and educational programs.

SanDISCA’s mission as the umbrella organization is to increase the visibility, effectiveness, efficiency and viability of the City of San Diego’s Sister City Societies and to guide the development of proposed Sister City relationships, thereby supporting their missions in the areas of cultural, educational, and economic relationships. To promote peace through mutual respect, understanding, and cooperation – one individual, one community at a time.

there is no more important work than that in which we are asking you to participate…the most worthwhile purpose there is in the world today: to help build the road to peace, to help build the road to an enduring peace.

Dwight D. Eisenhower
34th President of the United States

How do two cities become sister cities?

A relationship is formally created when the mayors or highest elected officials from two communities sign a memorandum of understanding establishing the sister city partnership. However, this is usually the result of a long process that involves the local sister city organization along with the municipality and other local institutions. Sister city relationships may develop from a number of sources, including but not limited to: preexisting mayoral relationships, trade relationships, historical connections, ancestral/demographic connections, expatriate communities, shared geographic/sector challenges, faith-based groups, and personal experiences ranging from study/work abroad to marriages.
