Relationship assessment

Mano River Union cooperation alongside conflict-era tensions

Liberia toward Sierra Leone

-20

Charles Taylor’s Liberian government supported Sierra Leone’s Revolutionary United Front during Sierra Leone’s civil war, contributing to severe bilateral tensions. Later regional cooperation through the Mano River Union provides a countervailing element.

Sierra Leone toward Liberia

+15

Sierra Leone participated in regional security efforts, including the ECOWAS intervention in Liberia during the Liberian civil war, and has cooperated with Liberia through the Mano River Union. The extent of later direct bilateral cooperation is unclear.

Overall relationship

0

The relationship combines a durable regional framework for cooperation, particularly through the Mano River Union, with the damaging effects of Liberia’s support for Sierra Leone’s rebel movement during the civil war. Postwar regional cooperation has reduced the prominence of that conflict, but its scope and durability are not clear enough to characterize the relationship as substantially cooperative.
