A sister city organization is a volunteer group of ordinary citizens who, with the support of their local elected officials, form long-term relationships with people and organizations in a city abroad. Each sister city organization is independent and pursues the activities and thematic areas that are important to them and their community including municipal, business, trade, educational and cultural exchanges with their sister city.
