What is twinning meaning?

Twinning refers to the practice of forming a partnership or sister city relationship between two towns or cities, typically in different countries. The aim of twinning is to promote cultural exchange and understanding, to encourage economic and trade relationships, and to foster cooperation in areas such as education, science, and the arts. Twinning often involves regular exchanges of civic officials and citizens, as well as joint projects and events. The concept of twinning was first pioneered in Europe after World War II as a way of promoting international peace and understanding. Today, thousands of towns and cities around the world are involved in twinning relationships.
