New Delhi: The US on Tuesday expressed concern over China's "provocative" and "dramatic" tactics in the South China Sea and said the American navy will shift 60 per cent of its maritime assets to the Pacific by 2020.
However, it underlined that the "rebalance" to the Asia and Pacific was not aimed at China but for its own economic growth.
Referring to China's ongoing territorial dispute with countries like Brunei, Taiwan, Malaysia, the Philippines and Vietnam over the South China Sea, a top Pentagon official said it was provocative.
"And it causes tensions to be raised in the South China Sea with all the other countries in the region. I am concerned about it. I think it is an issue of concern for all of us," Commander of the US Pacific Fleet, Admiral Harry Harris, told a group of journalists here.
Harris, the highest-ranking Asian-American in the history of the US Navy and the first to attain the rank of 4-star Admiral, said it "behoves" all countries concerned about freedom of navigation to pay attention to what China was doing in the South China Sea.
"It is dramatic. It is dramatic land reclamation. It is changing facts on the ground," he said.
Harris' visit to India comes just weeks after President Barack Obama said the US was "primed to unlock" the potential of relations with India as part of its rebalance to Asia and the Pacific.
He said that as part of the US rebalance, the Pacific fleet was going to get bigger.
"Right now, our goal is to have 60 per cent of the US Navy assigned to the Pacific fleet by 2020," he said, adding in a lighter vein that his area of responsibility extends from Hollywood to Bollywood and polar bears to penguins.
He said the US' submarine forces in the Pacific are at 60 per cent and surface vessel or ships at about 55 per cent.
"We will get extra ships. We are sending two extra ships to Japan. We are getting four submarines into Guam. We are going to bring an aircraft carrier around. US navy presence is going to increase over the course of this decade," he said.
Asked if this rebalance was aimed at a particular country, he said it is an American strategy that is not focused on any one country.
"It is not about China. It is really about us. It is about recognising that our economic future lies in the Pacific and the Indian Ocean," he said.
But even as he expressed concern about China's tactics in the South China Sea, he was quick to describe the presence of Chinese submarines in the Indian Ocean as "positive" since they are engaged in anti-piracy operations.
India has voiced concern over growing Chinese military presence in Indian Ocean.
