In June 1901, the Zongli Yamen was converted to the Waiwubu (外務部; foreign affairs ministry), with Yikuang still in charge of it. In December, Yikuang's eldest son, Zaizhen, was made a "beizi". In discussions over Manchuria, Yikuang "was bolder in resisting the Russians Li Hongzhang, though he was in the last resort weak and unable to hold out against pressure. The Japanese regarded him as a 'nonentity' but this judgment may have been influenced by the fact that he did not often accept their advice." He was also appointed to the Grand Council in March 1903. Later that year, he was put in charge of the finance and defence ministries – in addition to his position as head of the foreign affairs ministry. However, he was also relieved of his duties as a "yuqian dachen" (御前大臣) and replaced by his eldest son, Zaizhen.
