China not only is the country along the bank of the Sea of China including the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea, but also was the country along the bank of the Sea of Ochotsk and the Sea of Japan in history. But from then on, because of signing a series of unequal treaties between the government of the Qing Dynasty and some imperialistic countries, China gradually lost some parts of coastal areas and territorial seas and finally lost the sovereignty and the situation on the area of the Sea of Ochotsk and the Sea of Japan. Based upon the United Nations Maritime Convention, the Law of Territorial Sea and the Law of Exclusive Economic Zone & Continental Shelf which are promulgated by Chinese government, the formation and the evolution of the geographical pattern of Chinese coastal areas and territorial seas are discussed and studied. The geographical pattern of Chinese jurisdictional marine territory including territorial sea, contiguous zone, exclusive economic zone and continental shelf is roughly described in this paper.
