The research addresses "Saudi foreign policy towards Lebanon" from 1990 to 2016, in terms of its objectives and means. During this period, the "Kingdom of Saudi Arabia" focused on achieving political stability - in a fragile Lebanese environment suffering from deep sectarian and partisan divisions - by supporting the leadership of movements led by a component close to its orientations. This was in an effort by the Kingdom to strengthen "national unity", support Lebanon's sovereignty, and maintain and activate its institutions. This was based on the Kingdom's awareness of the importance of Lebanon's geopolitical position, its sponsorship of the "Taif Agreement" that ended the war there, and its ties and interests in Lebanon. The Kingdom supported "Lebanese security" through cooperation in areas most notably border control, preventing smuggling, and confronting threats. Economically, the Kingdom's objectives included promoting investments and trade exchange. and balancing external influence.
To achieve these goals, the Kingdom relied—in general—on diplomatic tools, such as the Taif Agreement, mediation, and public and religious diplomacy, in addition to economic tools, such as financial, investment, and development aid.
The study concludes that Saudi Arabia has adopted a comprehensive policy toward Lebanon. However, the effectiveness of this policy has faced internal and regional challenges that have limited its impact, necessitating a reconsideration of it, demonstrating greater flexibility and prudence in dealing with the complex Lebanese reality.
