Japan and the United States have reaffirmed their opposition to China's rapid land reclamation work around the disputed Spratly Islands in the South China Sea.

Tokyo and Washington oppose any attempt to change the territorial status quo by force, Defense Minister Gen Nakatani told reporters after meeting Saturday with U.S. Defense Secretary Ash Carter on the sidelines of the Asia Security Summit conference in Singapore.

Nakatani and Carter also met with Australian Minister for Defense Kevin Andrews for trilateral defense talks.
