The China-India Road,also called"Xikang-India Road","Yunnan-India Road"and"Stilwell Road",is an international passage between China and India built by the National Government during the Counter-Japanese War.After the fall of Guangzhou,China's international maritime transportation routes were blocked by the Japanese army.The National Government planned to build an international transportation route from Tibet to India in order to support long-term resistance to the Japanese invaders and to solve a series of internal,diplo-matic,and national defense problems.However,in order to maintain its own interests,the British govern-ment attempted to remove Tibet from being in alignment with China,the Soviet Union,and India,and placed it in a"buffer country"position.They were against the Nationalist Government's building of the China-India highway that would pass through Tibet.Under the instigation of the British,the local government of Tibet changed its cooperative attitude with the central government,refused entry to the China-India highway survey team,and thereby triggered repeated negotiations and conflicts among the National Government,the British government,the Indian government,and the local government of Tibet.It also led to a military confrontation between the Nationalist Government and the local government of Tibet,which prompted the establishment of the"Foreign Affairs Bureau"by the local government of Tibet.The National Government made a compromise by redesigning the south line of the China-India highway and temporarily abandoning the north line that pas-sed through Tibet.However,in the face of aggression from the Japanese army,the construction of the south line was forced to be suspended.After the outbreak of the Pacific War,with the intervention of the Allies,the China-India highway was finally completed,however,the route it took had undergone numerous changes,and its political and national defense functions were greatly reduced.
