鸦片战争之后,清政府与西方国家的交往日益频繁,西方近代国际法传入我国。处在外交前沿的李鸿章逐渐掌握了国际法的一些理论和原则,并尽可能运用国际法来维护国家利益,在几次对外交涉中还取得了一定的成效。 After the Opium War, the Qing government made more and more contacts with the western countries and the modern western international law came to our country. Li Hongzhang, who is at the forefront of diplomacy, has gradually mastered some of the theories and principles of international law and used international laws to safeguard national interests as much as possible. Some achievements have also been made in several foreign negotiations.
