Overall relationship

Relationship context
Overview
Tanzania and Uganda have a history that includes severe conflict, notably Uganda's 1978 invasion of Tanzania and Tanzania's subsequent military intervention. In later decades, the two governments have cooperated through East African regional integration and agreements on shared infrastructure, including the planned oil pipeline from Uganda to Tanzania's coast. This cooperation is substantial but does not erase the relationship's serious historical rupture.
