NEW DELHI: India is now actively discussing the possible sale of the indigenously developed Akash surface-to-air missile systems to Vietnam, even as the two countries steadily crank up their bilateral military ties with a watchful eye on a confrontational China in the Asia-Pacific region. With Beijing continuing to thwart New Delhi's bid to join the 48-nation Nuclear Suppliers Group and get Jaish-e-Muhammed chief Masood Azhar designated a terrorist by the UN, while also stepping up its naval forays into the Indian Ocean Region, India is responding by fast-tracking military ties with countries in China's own backyard. The expanding "strategic and military partnership" with Japan and Vietnam, in particular, has emerged a major thrust area. Sources say the discussions under way with Vietnam on the Akash area defence missiles, which have an interception range of 25-km against hostile aircraft, helicopters and drones, come after India earlier offered BrahMos supersonic cruise missiles and Varunastra anti-submarine torpedoes to the country. India, of course, will also begin training Vietnamese fighter pilots on its Sukhoi-30MKI fighter jets from this year, much like it has been tutoring sailors from that country on the intricate art of operating Kilo-class submarines for the last three years.
