The exercise will reportedly cover maritime manoeuvres, anti-submarine warfare and air defence techniques.

The United States, South Korea and Japan all agreed to hold annual military training in response to growing concerns regarding China.

Currently, Russian president Vladimir Putin is visiting the country and has signed a pact with North Korean leader Kim Jong Un.
