Abstract:After the May Thirtieth Incident, the deterioration of Sino-British relations is an indisputable fact. In order to improve the Sino-British relations and to consult all sectors in China about their views of the British Boxer Indemnity purposes, Willington, appointed by the British government, led a delegation to visit China in February 1926. Within five months, the delegation had done a lot of fruitful work, and had finished their basic mission. The report formed later became the basis of the 1930 Exchange in the Boxer Indemnity, which had been the foundation of the settlement of Sino-British Boxer Indemnity.
