China's submarines in Indian Ocean worry Indian Navy

An increasing number of Chinese submarines venturing into the Indian Ocean Region (IOR) pose a grave danger to India’s security interests, a classified defence ministry document has revealed.

Citing subsurface contact data shared by US forces, the document said at least 22 contacts were recorded with vessels suspected to be Chinese attack submarines patrolling outside Beijing’s territorial waters last year.

It has warned that the “implicit focus” of the Chinese navy appears to be undermining the Indian Navy’s edge “to control highly-sensitive sea lines of communication”.
