Tianjin and Montevideo are friendly associated on June, 26th,  in 1997.

Montevideo is the largest city, the capital and chief port of Uruguay. Montevideo is the only city in the country with a population over 1,000,000. It has a population of 1,325,968（2004) within the area of 530km2. According to Mercer Human Resource Consulting, Montevideo provides the highest quality of life in Latin America.

During World War II, a famous incident involving the German pocket battleship Admiral Graf Spee took place in Punta del Este, 200 kilometres (120 mi) from Montevideo. After the Battle of the River Plate with the Royal Navy and Royal New Zealand Navy on December 13, 1939, the Graf Spee retreated to Montevideo's port, which was considered neutral at the time. To avoid risking the crew in what he thought would be a losing battle, Captain Hans Langsdorff scuttled the ship on December 17. Langsdorff committed suicide two days later.

Montevideo has a very rich architectural heritage and an impressive number of writers, artists, and musicians. Uruguayan tango is a unique form of dance that originated in the neighborhoods of Montevideo towards the end of the 1800s. Tango, candombe and murga are the three main styles of music in this city.
