India’s navy on Wednesday simultaneously launched a submarine, a destroyer and a frigate built at a state-run shipyard, underscoring the importance of protecting the Indian Ocean region through which 95% of the country’s trade moves amid a strong Chinese presence. Defense Minister Rajnath Singh said that the Atlantic Ocean’s importance has shifted to the Indian Ocean region, which is becoming a center of international power rivalry. “India is giving the biggest importance to making its navy powerful to protect its interests,” he said.
