Town twinning has increasingly been used to form strategic international business links. For example, in the 1990s, when the Nottingham City Council in the UK considered installing a tram network, it consulted experts from its twin city of Karlsruhe, which has one of the most extensive and efficient tram networks in Germany. With assistance from Karlsruhe's specialist engineers, Nottingham completed its second tram line in 2013. In 2014, Bristol and New Orleans announced their intention to form a 'tuning' partnership based on a shared musical heritage and culture offer, at the initiative of Bristol Mayor George Ferguson. Annecy, France and Nerima, Tokyo have for several years shared a partnership based on their "co-existent animation industry".
