Japanese defense authorities have conveyed to their Chinese counterparts deep concerns about China's new law allowing its coast guard to use weapons.
The Japanese defense ministry officials discussed the situation in the East China Sea during a teleconference with the Chinese officials.
The Japanese officials strongly warned against any attempt to unilaterally change the status quo by force.
They also expressed strong concern about China's new coast guard law.
They said any attempts to harm the legitimate interests of Japan and other nations and stir tensions in the East and South China seas are totally unacceptable.
Meanwhile, the Japanese and Chinese officials shared the view that continuing dialogue is important.
The Japanese officials say both sides agreed to make progress on efforts to set up a hotline at an early date in order to prevent accidental clashes between the countries' defense personnel.
