Bourguiba and Nassar eventually came to find some common ground.[117] Although ties were broken under Nasser, and again under Anwar Sadat, on the whole relations between Egypt and Tunisia have remained mutually beneficial.

Tunisia's relations with Libya have been erratic since Tunisia annulled a brief agreement to form a union in 1974. Diplomatic relations were broken in 1976, restored in 1977, and deteriorated again in 1980, when Libyan-trained rebels attempted to seize the town of Gafsa. In 1982, the International Court of Justice ruled in Libya's favor in the partition of the oil-rich continental shelf it shares with Tunisia. Libya's 1985 expulsion of Tunisian workers and military threats led Tunisia to sever relations. Relations were normalized again in 1987. While supporting the United Nations sanctions imposed following airline bombings, Tunisia has been careful to maintain positive relations with its neighbor. Tunisia supported the lifting of UN sanctions against Libya in 2003, and Libya is again becoming a major trading partner. Currently, Tunisia has a maritime dispute with Libya.
