Jonas Mukamba Kadiata Nzemba

He ran for president in the 2006 presidential election.

When the city fell to the rebels on April 4, 1997, Nzemba was summoned to Goma to speak with Kabila, who held him for several days, prompting his family to purchase advertising in newspapers publicizing their concerns for his safety. Nzemba was released shortly after, but MIBA began making "voluntary contributions" to Kabila's war effort - totaling an estimated $5.5 million in 1997 and 1998.

During his time as head of MIBA, Nzemba is credited with creating the Conference pour le Developpement Economique de Kasai Oriental (CDEKO), a regional economic development group in the early 1990s. Nzemba also backed the creation of the University of Kasai, which was jointly sponsored by MIBA and the local Catholic church, and which became the home base of CDEKO. The new organization spearheaded economic growth in Mbuji-Mayi, helping support the development of new agricultural and beer industry expansion around the city, and launched Wetrafa, a locally owned airline.

Zaire's president Mobutu Sese Seko appointed Nzemba the chief executive officer of the state's main diamond mining company, the Societé minière de Bakwanga (MIBA) in 1986. Based in the city of Mbuji-Mayi, formerly Bakwanga, the company provided as much as 80 percent of the world's industrial diamonds, but other than mining operations which provided much-needed hard currency, the region was widely neglected by Mobutu and the central government. Throughout the 1980s and 1990s, Zaire and Mobutu paid little attention to Mbuji-Mayi, offering almost no money to build roads, schools or hospitals.

Jonas Mukamba Kadiata Nzemba (born January 4, 1931) is a politician from the Democratic Republic of the Congo and former CEO of the state-run diamond company. Between August 1965 and October 1968 he was governor in turn of South Kasai, Kasaï-Oriental, Équateur and Orientale Province. He was again governor of Équateur Province between 27 August 1980 and 19 March 1983.
