File picture shows fishing boats in the bay of the Ly Son islands of Vietnam
Fishing boats are seen in the bay of the Ly Son islands of Vietnam's central Quang Ngai province, in this file picture taken April 10, 2012. China said on November 30, 2012, that it attached great importance to freedom of navigation in the South China Sea after state media said police in its southern island province of Hainan will board and search ships which illegally enter what China considers its territory in the disputed waters.
