Bujumbura, formerly Usumbura, is the economic capital, largest city and main port of Burundi. It ships most of the country's chief export, coffee, as well as cotton and tin ore. Bujumbura was formerly the country's political capital. In late December 2018, Burundian president Pierre Nkurunziza announced that he would follow through on a 2007 promise to return Gitega its former political capital status, with Bujumbura remaining as economical capital and center of commerce. A vote in the Parliament of Burundi made the change official on 16 January 2019, with all branches of government expected to move to Gitega within three years.
