China is strengthening its maritime surveillance capacities to deal with the complicated sea disputes and safeguard the country's maritime rights, a senior official said on Sunday.

The China Marine Surveillance fleet will enhance patrols off the important islands to demonstrate the country's sovereignty, Xiao Huiwu, deputy director of CMS told China Daily.

"CMS will stop all the illegal activities in the country's territorial waters, guaranteeing China's maritime rights," Xiao said.
