The Navy had last year organised the conference on board India's aircraft carrier INS Vikramaditya at Sea, off the coast of Kochi.
While the dates and location of this year's conference are yet to be finalised, sources said it could be held under the aegis of the Eastern Army Command which is involved in anti-insurgency operations in the northeast and a major part of the borders with China.
Interestingly, Lt Gen Praveen Bakshi, who is slated to be the next Army Chief, heads the Eastern Command.
The conference is attended by Prime Minister, Defence Minister Manohar Parrikar and other senior members of the Cabinet.

ISKCON spiritual leader and founder of Govardhan Eco
Village, Maharaj Radhanath Swami advocated holistic use of water for human survival, saying every drop of water is precious and should not be wasted.
Water, he said, was one of the basic necessities of life and the people are dependent on it spiritually, emotionally and physically.
ISKCON's Govardhan Eco-village at Wada near Mumbai, has undertaken a water resources programme which focusses on planning, developing, distributing and managing the optimum use of water resources, Swami added.
Director of Council for Scientific and Industrial Research (CSIR) and National Environmental Engineering Research Institute (NEERI) Dr Rakesh Kumar said water in the soil nourishes crops so even a small patch of grass holds moisture and equally important for the people would be to conserve invisible water in the air.
Kumar said he was happy to note that Maharashtra government has not allowed industries in water catchment areas so there was no water contamination.
The conference concluded with a panel discussion on 'Integrated Water Resource Management and Sustainable Development'.
Experts also participated in another panel discussion - 'Protecting our water future'.
