China-Japan diplomatic relations go sour over conflict off disputed island

The collisions between two Japanese patrol boats and a Chinese fishing boat in waters off the Diaoyu islands in the East China Sea, and the arrest of China fishermen by Japan’s Coast Guard have led to sour diplomatic relations between both countries.

According to Japanese media, the captain was arrested on suspicion of "obstructing public duties" in connection with collisions with Coast Guard patrol boats.

The trawler captain, a 41-year-old Chinese national, was taken to Ishigaki Island in Okinawa Prefecture at around 7 a.m. and the 14 Chinese crew were also taken to Ishigaki but barred from disembarking.

China has expressed grave concern over the incidents on Tuesday. Chinese Vice Foreign Minister Song Tao summoned Japanese Ambassador to China Uichiro Niwa and lodged solemn representations on Japan's interception of Chinese fishing boats.
Song urged Japanese patrol boats to stop their illegal interception against Chinese fishing boats.

"The Diaoyu islands and its adjacent islets have been Chinese territory since ancient times," Foreign Ministry spokeswoman Jiang Yu said at a regular press conference on Tuesday. She further said: "We demand Japanese patrol boats refrain from so-called law enforcement activities in waters off the Diaoyu islands and refrain from actions that would threaten the security of Chinese fishing boats and their crew."

"We will closely follow the situation and reserve our right to take further actions," Jiang added.

The background history of the dispute over the island.

The Diaoyu islands are situated 120 nautical miles northeast of Taiwan, 200 nautical miles west of China's mainland and 200 nautical miles east of Japan's southernmost island Okinawa. China claims the islands belonged to it since ancient times.

Geologically the islands are close to Taiwan. The waters around the islands are 100 to 150 meters deep and there is a 2,000-meter-deep oceanic trench between the islands and Japan's Okinawa islands.

Fishermen from China's Taiwan and Fujian and other provinces conducted activities such as fishing and collecting herbs in this area since ancient times.
China says the islands appeared on China's map since the Ming Dynasty (1368-1644). There are records about the islands in a book published during the rule of Yong Le (1403 to 1424) in the Ming Dynasty, more than 400 years before Japan claimed discovery of the Diaoyu islands in 1884.

After the Ming Dynasty, the islands were recorded in many historical documents. On a map published by Japan between 1783 and 1785, marking the boundary of the Ryukyu Kingdom, the Diaoyu islands were shown as belonging to China.
Japan never questioned China's sovereignty over the islands before the Sino-Japanese war of 1894-1895. In April 1895, the government of the Qing Dynasty was forced to sign the Treaty of Shimonoseki, under which China ceded the whole island of Taiwan and its surrounding islands including the Penghu Islands to Japan.
Only since then has Japan had its own name for the area where the Diaoyu islands are located. Before that, Japanese maps marked the islands by their Chinese names.

Japan was occupied by the United Sates after it was defeated in the Second World War. In 1951, Japan and the United States illegally signed a treaty in San Francisco without the presence of China, which was one of the victor countries in the Second World War.

Although article two of the treaty said that Japan surrendered its claim over Taiwan and the Penghu islands, article three wrongly assigned the Diaoyu islands, which Japan had stolen from China, and other islands, to the Ryukyu zone which was under U.S. control.

The then Chinese Premier Zhou Enlai lodged a strong protest and said the Chinese government would never recognize the San Francisco Treaty.
In a statement on territorial waters in 1958, the Chinese government said that Japan should return all the territory of the People's Republic of China including Taiwan and the islands around it to China.

That means there is no room for argument that the Diaoyu islands have historically been a part of China's territory.
