Angola–DR Congo border

A border in two pieces: the main line, from the mouth of the Congo along great rivers such as the Kwango and Kasai to Zambia, and a short loop around Angola’s exclave of Cabinda, cut off by Congo’s narrow corridor to the sea. In 2018 Angola expelled some 330,000 Congolese across it in a single month.

A corridor and an exclave

Portugal’s colony of Angola dated back to a charter of 1575 and later extended north of the Congo River to Cabinda. When King Leopold’s Congo was recognised in 1884–85, a convention of 14 February 1885 split the coast: the Congo state recognised Portugal’s claim to Cabinda, and Portugal guaranteed it a narrow corridor of land to the sea. So the border runs in two parts, about 140 miles around Cabinda and about 1,420 miles inland from the Atlantic along the Congo, the parallel of Noqui, the Kwango, the Kasai and drainage divides to Zambia. Conventions of 1891 added detail.[1]

The 2018 expulsions

In October 2018 an Angolan expulsion order aimed at irregular migrants sent some 330,000 people across the border into Kasai, Kasai Central and Kwango provinces. At the border town of Kamako the UN human rights office heard reports of excessive force by Angolan security forces, verified six deaths, and heard allegations of extortion and arbitrary detention by Congolese forces on arrival.[2]

“In expelling such a massive number of people in such a short time, Angola has placed tens of thousands of families at severe risk”[2]
