Defence Minister of Japan has warned China over the penetration of Chinese in Japanese Land, Japan has also claimed it land and has strongly stated to protect it.
Nobuo Kishi said the territories, known as the Diaoyu Islands in China, unquestionably belong to Japan and warned any provocation from Beijing will be fully matched.
His warnings come as a new three-way nuclear submarine pact between the US, UK and Australia aimed at combatting China was unveiled, to the delight of Japan and Taiwan.
It has added state-of-the-art F-35 fighter jets and converted warships to aircraft carriers, while building new destroyers, submarines and missiles.
Kishi: ‘Against Chinese action to Senkaku Islands and other parts of the East China Sea… we have to demonstrate that the government of Japan is resolutely defending our territory with the greater number of Japanese coast guard vessels than that of China.
‘There is no territorial dispute relating to the Senkaku Islands between Japan and other countries.’
The uninhabited islets in the East China Sea, controlled by Japan but claimed by China, have been at the centre of a long-standing dispute that has plagued the relations between Beijing and Tokyo for years.
They are located 1,200 miles southwest of Tokyo but only a third of that distance from Shanghai.
They are considered to have great economic and strategic values because they are close to important shipping lines and offering rich fishing grounds.
China and Japan both claim sovereignty over the islets, which are under Japanese administration, preventing wide-scale exploration and development of oil and natural gas in the East China Sea.
During a row over the territories in 2012, it led to mass protests in China where Japanese cars, shops and restaurants were destroyed and the embassy targeted.
China has been just as ardent in its claims as Japan, saying last year: ‘The Diaoyu Island and its affiliated islands are an inherent part of China’s territory, and it is our inherent right to carry out patrols and law enforcement activities in these waters.’
Japanese authorities say that this year alone, Chinese Coast Guard vessels have ventured into Japanese waters or 12 nautical miles of Japanese land more than 88 times.
Experts believe China intends to put forces in and around contested areas.
They are also exerting force over Taiwan, which Beijing views as part of China even though it has never been governed by the CCP.
China has regularly sent warplanes and ships towards Taiwan, which has in turn alerted its air defences, with US ships often patrolling the contested South China Sea.
Kishi said: ‘What could happen in Taiwan could likely be an issue for Japan, and in that case, Japan will have to take the necessary response to that situation.’
As tensions simmer, China is also threatening to send its Navy into Hawaiian waters in the latest round of sabre rattling in the Pacific after Australia, the US and Britain announced a new naval alliance in the region.
Four Chinese vessels have already been spotted sailing off the coast of Alaska this week in a display of naval power amid increasing tensions as a global nuclear submarine pact was signed to take on Beijing.
A Chinese guided-missile cruiser, guided-missile destroyer, general intelligence vessel, and an auxiliary vessel were spotted off the coast of Alaska’s Aleutian Islands during surveillance operations in the Bering Sea.
The provocation came as China’s state-run newspaper threatened to send warships to Hawaii and Guam in response to US moves in the South China Sea.
