evidence: The two countries, however, have a portion of their border largely undetermined at the Ilemi (also called Elemi) Triangle, a sparsely populated area of about 14,000 square kilometres. Ilemi is on the fringe of southern South Sudan, which is believed to be rich in oil, and to the north of Turkana, a Kenyan county where Tullow Oil discovered oil in 2012. [...] The name Ilemi is believed be from a famous chief of the Anuak, a community on South Sudan’s boundary with Ethiopia. The triangle was named in honour of chief Ilemi Akwon.
