An active-duty missile corvette of the Indian Navy is on its way to Vietnam as a gift, the first warship given by India to any country. The domestically built corvette INS Kirpan left India's east coast on Wednesday (Jun 28), the navy said. India and Vietnam have strengthened their ties in recent years, with a special focus on defence, as both countries are concerned over an increasingly assertive China. India has given smaller boats and military equipment to countries like Maldives and Mauritius in the past and a submarine to Myanmar.
