The 247 kilometer (153 mile) boundary between Namibia and Zambia runs generally west-to-east, first following a straight line from the tripoint with Angola to the Zambezi River, and then following the Zambezi River to the tripoint with Botswana. Namibia and Zambia have relatively good relations, and Zambia supported Namibian independence from South Africa during the South African Border War. Namibia and Zambia do not dispute the location of the boundary.
