膠州湾租借地
The area was transferred to German rule on a 99-year lease (or until 1997, as the British did in Hong Kong's New Territories and as the French did in Kouang-Tchéou-Wan), and it became known as the Kiautschou Bay concession. The village of Tsingtau became the German colony of Tsingtau, and the area became a focus for German commercial development in China, while for the Imperial German Navy it was the base for their Far East Squadron.
