“外须和戎，内须变法”的洋务思想，是李鸿章开展洋务新政的一条基本纲领。“外须和戎”承认中外的客观差距，希望求得和平环境，徐图“自强”，有其合理的一面；“内须变法”不失为一种积极的思想，即通过变法来达到“器精防固”，使列强不敢起轻视窥伺之心，以实现长治久安。 The foreign affairs thinking that “we must strive for a harmonious development within and outside of China must be a basic program for Li Hongzhang to launch a new administration of foreign affairs.” “Foreign Must and Military Diplomacy” recognize the objective gap between China and the rest of the world and hope to find a peaceful environment. However, Xu Tzu’s “self-improvement” has its reasonable side. “The internal reform must be a positive thinking, that is, through the reform, Prevent corruption, ”so that the powers can not afford to underestimate the purpose of snooping in order to achieve lasting peace and stability.
