The Japanese government has affirmed a new guideline to enhance its surveillance and guard system over its remote islands, as well as disputed territories with its neighboring countries.

Under the new surveillance system, large surveillance vessels will be sent to patrol surrounding areas of the disputed islands and there will be a mechanism of 24-hour aircraft surveillance.

The move risks further worsening Japan's ties with its neighbors including China and South Korea.

Ties between China and Japan have been strained since 2012 when the Japanese government unilaterally moved to nationalize part of the Diaoyu islands that are the inherent Chinese territory.

China has repeatedly made clear that any provocative moves by Japan concerning the Diaoyu Islands are not helpful in resolving the dispute.
