This thesis focuses on the border dispute between Malawi and Tanzania that has been for decades without resolution. The border dispute between these two countries is traced from 1890 during the colonial era and concerns Lake Nyasa. Both countries share the Lake, and each claims its ownership. Tanzania is claiming that the correct boundary runs down the middle of the Lake whereas Malawi is claiming the whole part of the Lake to the peripheral. This study uses qualitative research methodology using Cameroon-Nigeria and Guinea Bissau- Senegal as comparable cases to examine as examples to what might be the best solution to the border dispute between Malawi and Tanzania. It seeks a solution using the instruments of national power Diplomacy, Information, Military and Economic.
