A sister city or a twin town relationship is a form of legal or social agreement between two geographically and politically distinct localities for the purpose of promoting cultural and commercial ties.
While there are early examples of international links between municipalities akin to what are known as sister cities or twin towns today dating back to the 9th century, the modern concept was first established and adopted worldwide during
World War II

The tablecloth can now be seen at the Panorama Museum of the Battle of Stalingrad. The twinning between Coventry and Stalingrad was formalised in 1944 and, after the end of the war, similar links were established to foster friendship and understanding among former foes as an act of peace and reconciliation, with new twinnings between Coventry and German cities:

in 1956. In 1957, Coventry was officially twinned with Belgrade, however, the link actually dates back to 1953 when the Yugoslav Ambassador visited Coventry and offered a gift of timber from his native country for use in the new Civic Theatre, which when finished was named The Belgrade Theatre.
The purpose of twinnings then got expanded to encourage trade and tourism or to reflect other links, such as towns sharing the same name or migration links. By the 2000s, town twinning became increasingly used to form strategic international business links among member cities, and may include localities of any scope such as villages, prefectures, or countries.

Germany, Poland, and the Czech Republic use ''Partnerstadt'' (De) / ''miasto partnerskie'' (Pl) / ''partnerské město'' (Cz), which translate as "partner town" or "partner city". France uses ''ville jumelée'' (jumelage, twinned town or city), and Italy has ''gemellaggio'' (twinning) and ''comune gemellato'' (twinned municipality). In the Netherlands, the term is ''partnerstad'' or ''stedenband'' ("city bond" when providing mutual support). In Greece, the word αδελφοποίηση (''adelphopiisi''fraternisation) has been adopted. In Iceland, the terms ''vinabæir'' (friend towns) and ''vinaborgir'' (friend cities) are used. In the former

s. According to Rodrigo Tavares, the earliest formal attempts to establish city diplomacy across national boundaries took place in the 19th century. Only a handful of cities were involved in the 19th-century efforts; it wasn't until the turn of the millennium that it became much more common. The first priority of those carrying out city diplomacy typically overlaps with the core aims of municipal government – improving the lives of local residents. Yet they will often collaborate with peers in other cities to work on issues of planet-wide concern, such as efforts to address climate change.
The phrase "city diplomacy" is formally used in the workings of the United Cities and Local Governments and the C40 Cities Climate Leadership Group, and is recognised by the USC Center on Public Diplomacy. A March 2014 debate in the British

Within Europe, town twinning is supported by the European Union. The support scheme was established in 1989. In 2003 an annual budget of about was allocated to about 1,300 projects. The Council of European Municipalities and Regions also works closely with the commission (DG Education and Culture) to promote modern, high quality twinning initiatives and exchanges that involve all sections of the community. It has launched a website dedicated to town twinning. As of 1995, the European Union had more than 7,000 bilateral relationships involving almost 10,000 European municipalities, primarily French (2837 twinnings) and German (2485 twinnings).

has been used to celebrate twin town links, for instance in the form of seven mural paintings in the centre of the town of Sutton, Greater London. The five main paintings show a number of the main features of the London Borough of Sutton and its four twin towns, along with the heraldic shield of each above the other images. Each painting also features a plant as a visual representation of its town's environmental awareness. In the case of Sutton this is in a separate smaller painting (above its main one) showing a beech tree, intended as a symbol of prosperity and from which Carshalton Beeches in the borough derives its name.

China's sister city relationships are managed by the Chinese People's Association for Friendship with Foreign Countries, a united front organization. Town twinning is supported in Japan by the Council of Local Authorities for International Relations, a joint agency of local governments established by the Japanese government in 1988 (similar to Sister Cities International, its counterpart in the US). In Japan, the international city relations may be split into multiple terms, such as Sister Cities, Friendship Cooperation Cities, Business Partner Cities (BPC), Memorandum of Understanding (MOU), Sister Ports / Friendship Ports, etc. Japan and China mostly use the term "friendship cooperation cities" rather than "sister cities," as the Japanese and Chinese words for sisters, "姉妹 / 姐妹" (reading: shimai / jiěmèi, literally elder sister and younger sister), could imply a hierarchical relationship. More recently, Tokyo has begun to actively promote 'city diplomacy' with other global cities at the initiative of its governor Yoichi Masuzoe.
