On 30 May 1925 an incident took place at Shanghai in which a British police captain fired into a Chinese mob, resulting in the death of some Chinese. This gave a great fillip to anti-foreign movement in China. The students, merchants and traders shouted “Foreigners have shot down Chinese citizens on Chinese soil”.

Soon anti-foreign riots bioke out at Chinkiang, Hankow, Kiukiang and Chunking. The radical sections demanded return of all conces­sions, the expulsion of foreign troops and immediate abolition of extra­territoriality. Foreign lives and property in China was greatly jeopardized and the Chinese organized an effective blockade of Hongkong and boycott of British goods. This blockade lasted for over a year. What is really surprising that British took no retaliatory action.
