Eleven Chinese warships sailed into the East Indian Ocean this month, a Chinese news portal said, amid a constitutional crisis in the tiny tropical island chain of the Maldives now under a state of emergency.

A fleet of destroyers and at least one frigate, a 30,000-ton amphibious transport dock and three support tankers entered the Indian Ocean, news portal Sina.com.cn said, without linking the deployment to the crisis in the Maldives or giving a reason.

"If you look at warships and other equipment, the gap between the Indian and Chinese navy is not large," Sina.com.cn said Sunday.
