The only battle to be fought in the Far East during World War One had a profound and lasting impact on Chinese-Japanese relations. Germany controlled the port of Tsingtao (modern day Qingdao) on the east coast of China until an Anglo-Japanese force invaded in September 1914.

As part of a BBC series looking at stories beyond the trenches, Carol Yarwood from the BBC Chinese service recounts the siege of Tsingtao.
