The Lebanese-Syrian Higher Council, established on May 22, 1991, under the Treaty of Brotherhood, Cooperation, and Coordination between Lebanese President Elias Hrawi and Syrian President Hafez al-Assad following the end of the Lebanese Civil War, served as the highest official framework for organizing relations between Lebanon and Syria.

The council was responsible for monitoring the implementation of agreements and coordinating joint activities between the two capitals. Nasri Khoury held the position for many years.

During the 1990s and early 2000s, the council was a key tool for coordination between Beirut and Damascus, especially amid the Syrian military presence in Lebanon. It oversaw sensitive security and economic files and contributed to formulating many bilateral agreements.

However, after the withdrawal of Syrian forces from Lebanon in 2005, the council’s role clearly declined, and in subsequent years its activity was limited to symbolic and administrative tasks without an official cancellation at that time.
