Sister Cities International is an organization that brings together communities from different areas and different cultures.Sister-city relationshipscan help communities learn from each other and solve problems together.

Often these partnerships are based on special projects or exchanges. People share their knowledge in areas like education, government, business or technology.

Building sister-city relationships was one of the ideas for the "People-to-People" program created by President Dwight Eisenhower. He established the program at a White House conference held on September 11 and 12, 1956.

President Eisenhower wanted to connect citizens who shared an interest in other cultures. He wanted to increase international understanding and friendship through educational, cultural and humanitarian activities. He believed that citizen diplomats could help build peace.

Sister Cities International is a non-profit organization based in Washington, D.C. The group is involved with programs in 134 countries.

Today, 700 American communities have partnerships with almost 1,800 communities in other countries.

Atlanta, Georgia, for example, has 18 sister-city partnerships. One is with Brussels, Belgium. Another is with Lagos, Nigeria. These two relationships have existed for more than 30 years. The areas they involve include economic development and trade.

Matthew Corso works for Sister Cities International. He says that within the past 15 years, more American cities have created partnerships in developing countries. Projects have involved water quality, health care and good government, for example. In Africa, projects might also deal with AIDS and HIV.

Mr. Corso says that sister-city partnerships usually result from local connections. Local governments also become involved and many provide some leadership. But, generally, citizen groups are responsible for organizing and supporting partnerships.

Some sister-city relationships are 50 years old. And now there are even "cyber sister cities" -- partnerships created over the Internet.
