What Is a Sister City?

A Sister City is a broad-based, long-term partnership between two communities in two countries. These two cities and their citizens formally join to learn more about each other and to develop friendly and meaningful exchanges in a wide variety of areas. Exchanges may include, but are not limited to, government, business, economic, cultural, educational and social relationships.

A Sister City relationship is only officially recognized once the highest-ranking government official of each city sign off on an agreement to become a "Sister City".  The affiliation not only involves the governments of each city but also a citizen committee in each city who is engaged in ongoing and continuing projects of mutual interest through continuous contact with one another.


Arlington Sister City Association (ASCA) is a nonprofit organization affiliated with Arlington County, Virginia. Established in 1993, ASCA supports and coordinates the activities of Arlington County’s five Sister Cities: Aachen, Germany; Coyoacán, Mexico; Ivano-Frankivsk, Ukraine. Reims, France; San Miguel, El Salvador. ASCA works to enhance and promote the region’s international profile and foster productive exchanges in education, commerce, culture and the arts through a series of activities.



The Beginning

The Arlington Sister City Association (ASCA) was established in May 1991 with the appointment of the Arlington County Sister City Commission who was tasked to explore the benefits of various exchanges and the potential to increase recognition of Arlington as a regional international center through sister city relations and activities. 



The Commission formalized its first partnership with the Aachen, Germany in June 1993 at Aachen, and a reciprocal visit and ceremony in Arlington in May 1994. ASCA became an independent, nonprofit organization in August 1993.



In July 1995, ten Arlington delegates visited Coyoacán, a Federal District of Mexico City, to discuss making Coyoacán Arlington’s second sister city. At a reciprocal set of meetings with Arlington business leaders, together with several cultural events and a tour of the county, delegates formalized the partnership at Arlington House and the Arlington County Board officially adopted Coyoacán as a sister city on October 7, 1995. Coyoacán officials adopted Arlington as its first sister city on June 22, 1996.



Arlington began communications with Reims, France in 1996. The first Arlington delegation visited Reims in 2000 and established a high school exchange program. A signing ceremony took place at Reims on August 28, 2004, which coincided with the 60th anniversary of the liberation of Reims by U.S. forces in August 1944. A reciprocal visit to Arlington took place in June 2005, culminating with a signing ceremony at Arlington House on June 12, 2005.


San Miguel

An Arlington delegation visited San Miguel, El Salvador in September 2005 and signed a preliminary agreement, followed by a reciprocal visit and ceremony in Arlington in June 2006.  Arlington’s relationship with San Miguel is supported by a vital local community of Latin American residents and businesses.



Ivano-Frankivsk, Ukraine became a sister city in May 2011 when the agreement was signed at the annual convention of the Sister Cities International in Arlington Virginia.
