The Chinese Foreign Ministry called the Diaoyu Island an integral part of China

The Diaoyu Islands (Japanese name Senkaku) are an integral part of China, Chinese Foreign Ministry spokesman Zhao Lijian said at a briefing on Friday, commenting on the joint statement on the results of the 28th Japan-EU summit.

On Thursday, the 28th Japan-EU summit was held in Tokyo, following which a joint statement was published, from which it follows that Japan and the European Union express serious concern about the situation in the East China Sea, including the area around the Senkaku Islands, as well as China's increased military activity.
"The Diaoyu Islands are the ancestral territory of China, regardless of what others say, it is impossible to change the objective fact that the islands belong to China," the diplomat said.
Zhao Lijian also accused Japan and the EU of denigrating China, interfering in its internal affairs, as well as provoking regional confrontation at the last summit.
"China strongly opposes this," he added.
The Senkaku Islands (Chinese name Diaoyu) are the subject of a territorial dispute between China and Japan. Japan claims to have occupied them since 1895, Beijing recalls that on the Japanese maps of 1783 and 1785, the Diaoyu (Senkaku) are designated as Chinese territory. After World War II, the islands were under Japan holding them illegally. Tokyo believes that China and Taiwan have been claiming the islands since the 1970s, when it turned out that their waters are rich in minerals. An even greater aggravation of the territorial dispute occurred under the control of the United States and were transferred to Japan in 1972. In Taiwan and mainland China, it is believed that after the Japanese government bought three of the five islands from a private Japanese owner in 2012, thus emphasizing their state status.
