India and Australia have agreed to hold joint naval exercises off the east coast of India starting September 12th. The exercise will concentrate on surface and aerial anti-submarine exercises. Australia will send a submarine and an AP-3C submarine hunting aircraft. India will send surface warships and one of its new P-8I submarine hunting aircraft. While China is Australia’s biggest export customer (mainly for raw materials) Australia agrees with India that the increasingly aggressive Chinese naval operations are a threat to all nations in the region. In October India will hold similar exercise with Japanese and American naval forces.
