Chongqing and Dar es Salaam of Tanzania in 2013 signed a Memorandum of Understanding (MOU) on establishing friendly relations and cooperation.

Dar es Salaam (Haven of Peace in Arabic) was founded in 1862 by Sultan Seyyid Majid of Zanzibar on the site of the village of Mzizima. Mzizima's history dates back to the time when the Barawa people started to settle and cultivate the area around Mbwa Maji, Magogoni, Mjimwema, Gezaulole and Kibonde Maji Mbagara.

Dar es Salaam is Tanzania's financial and political hub despite having lost its status as official capital to Dodoma in 1973.
