鲁哈尼在第一任期内完成了与美国的核谈判，缓和了与美国的关系。这使伊朗与欧洲的政治、经贸关系迅速解冻，而此后伊朗出席叙利亚和谈更提高了伊朗的国际影响力，彰显了伊朗的软实力。伊朗与欧洲交好，也使伊朗可以平衡之前对中国、俄罗斯的单方面依赖。在中东地区，伊朗支持的什叶派政府、组织纷纷得势，危及逊尼派领袖沙特阿拉伯在中东的优势地位。鲁哈尼的第一个任期内，伊朗实力的增长加剧了伊朗与沙特之间的竞争。伊朗与沙特关系的紧张，直接影响了伊朗与海湾石油国家的关系，也使叙利亚战争以及也门内战逐渐发展为伊朗与沙特的代理人战争。
During his first term，Rouhani completed nuclear negotiations with the United States and eased relations with the United States. This led to the rapid thawing of the political and economic relations between Iran and Europe，and then Iran's participation in the Syria peace talks enhanced the international influence of Iran and highlighted the soft power of Iran. Iran's good relations with Europe also enable Iran to balance its previous unilateral dependence on China and Russia. In the Middle East，the Shiite government and organizations supported by Iran are gaining momentum and jeopardize Saudi Arabia's dominance in the Middle East. During his first term of office，the growth of Iran's strength increased the competition between Iran and Saudi Arabian.The tension between Iran and Saudi Arabia has a direct impact on the relationship between Iran and the Gulf oil countries，as well as the Syrian war and the gradual development of the civil war in Yemen as the agent war between Iran and Saudi Arabia.
