So far, historians assess lowly of diplomatic performance of the late Ching government and neglect the continuity of diplomacy between Ching and the Republican era. This article consults with diplomatic archives of Ching government, works of both diplomats and scholars, and newspapers of 1860s to 1911, to explore the development of ideas and deeds of Treaty Revision in that period. Ching officials' ideas on revising treaties started from those ministers sent abroad in late 1870s. The first official try to revise treaty began in late 1890s but suspended soon. Sino-Russia negotiations of 1911 was the only formal case that showed Ching government's will and deed on treaty revision. Although after several months painful talks in St. Petersburg negotiations have been disrupted by the Chinese Revolution but it already paved the way for treaty revision of the Republican era.
