Boxer Protocol
Yikuang was then sent by Empress Dowager Cixi, along with Li Hongzhang, to negotiate for peace with the Eight-Nation Alliance after they invaded Beijing in 1901. Yikuang and Li Hongzhang signed the Boxer Protocol on 7 September 1901. During the conference, Yikuang was seen as a representative while the actual negotiations were done by Li Hongzhang. Returning to Beijing as a senior member of the imperial court, Yikuang persisted in his old ways, and was despised by not only reformers, but also by moderate court officials.
