The boundary between modern-day Libya and Sudan is based on the former colonial frontiers between Italian Libya and Anglo–Egyptian Sudan. It was delimited in 1934 with the transfer of the Sarra Triangle from British to Italian control. The international frontier extends for 381 kilometers from the tripoint with Egypt in the north to the tripoint with Chad in the south, following a series of meridians and a parallel. It is possible that the boundary was partially demarcated by colonial surveyors, but Libya and Sudan have not made any efforts to re-demarcate the boundary since independence, likely due to the multitude of ongoing conflicts that have embattled both States. Despite unstable relations, the boundary itself does not seem to be a source of conflict for either Libya or Sudan.
