evidence: Kafia Kingi area (Also spelled Kafia Kinji, Kafiya Kinji) This is the largest of the regions disputed between Sudan and South Sudan, with its own confused history. Sudan seems to have transferred the area from the south's Western Bahr el Ghazal state to the north's South Darfur state in 1960 - too late to make it part of the north under the 1956 borders. However, some documents suggest it may have already been transferred by the British in the 1930's (before 1956, making the transfer still valid today). In addition to the town of Kafia Kingi itself, the area also includes the copper mining town of Hofrat en Nahas (also Hufrat an Nuhas, Hufrat al Nahas) and the border town of Kafan Dabi (also Kafindabei, Kafn Dubai, Kafan Dibi), which was recently "recaptured" by the north.
