In 2018， Russia further strengthened its influence in the Middle East. On the one hand， it actively participated in the hot issues in the Middle East， strove to mediate and solve the common problems in the security field. On the other hand， Russia did not clamp down by Sunni-Shia cracks and made extensive alliances in the region. In general， Russia has been pragmatically coping with complex geopolitical environments and its military operations， diplomatic efforts and economic participation have worked together. While the United States is strategically contracting and phasing out in the Middle East， Russia is increasingly seen as a responsible power in the region. Russia's successful power projection has brought its influence in the Middle East to the peak in the post-Cold War era and further reshaped the regional balance of power.
