The Diaoyu Islands are a group of uninhabited islands located roughly due east of mainland China, northeast of Taiwan, west of Okinawa Island, and north of the southwestern end of the Ryukyu Islands. They are currently controlled by Japan, which calls them Senkaku Islands. Both China and Taiwan claim sovereignty over the islands.
Marines, drones proposed for Japanese military
Government paper suggests ways to strengthen country's military, but falls short of mentioning 'pre-emptive strike capability' for defence

Japan should acquire amphibious units like the US Marines and surveillance drones, a government paper is expected to say, as a territorial dispute with China rumbles on.
The interim report, to be issued as early as today by the Defence Ministry, will also promote "the need to boost a comprehensive capability of containment" as part of anti-ballistic missile measures against North Korea, reports said.
The phraseology falls short of any mention of "pre-emptive strike capability", but reflects an on-going debate in Japan's defence community about the need to re-interpret aspects of the pacifist country's military stance.
Nationalist Prime Minister Shinzo Abe has said Japan needs to discuss the idea of having some kind of first strike provision if it is to effectively counter threats from North Korea's nuclear and missile programmes.
However, observers say he must tread carefully. Japan's constitutionally-prescribed pacifism enjoys wide support in the country at large and is particularly cherished by Abe's coalition partners, a centrist Buddhist party.
The Asahi and Yomiuri, influential papers on the left and right respectively, say the interim report advocates a US Marines-like amphibious force, capable of conducting landing operations on remote islands.
It also suggests looking at the introduction of a drone reconnaissance fleet that could be used to monitor Japan's far-flung territory.
The report will be reflected in Japan's long-term defence outline that is expected to be published towards the end of this year, a defence ministry spokesman said.
China has become increasingly active in the seas surrounding Japan, including waters near the Tokyo-administered Senkaku islands in the East China Sea, which Beijing claims as the Diaoyu islands.
The row over their ownership, which began decades ago, erupted again last September when Japan nationalised three of the islands. It took another turn on Wednesday when possibly-armed Chinese coastguard vessels sailed through nearby waters for the first time.
Later in the day Tokyo scrambled fighters to shadow a Chinese reconnaissance aircraft that flew in international airspace between two Okinawan islands.
It was the first time Beijing had sent a military plane through the gap and out to the Pacific Ocean, Tokyo officials said, adding they saw it as a sign of "China's ever-growing maritime advance".
Abe expressed concern over the sighting.
"It was an unusual action that we have never seen before. We'll keep monitoring it with great interest," Abe said yesterday before leaving for a trip that will take him to Malaysia, Singapore and the Philippines.
In Beijing, the Defence Ministry issued a statement defending the right of its aircraft to operate in the area.
The training flight was a "scheduled annual arrangement that was not directed at any specific countries or targets and was in accordance with relevant international law and practice," the Global Times newspaper quoted an unidentified ministry spokesman as saying.
