The Associated Press reports at first glance, it looks like a diplomatic love-fest. There was Chinese President Xi Jinping, toasting the birthday of Indian Prime Minister Narendra Modi in a quiet dinner earlier this week in Modi's home state. There were the two leaders, deep in conversation as they walked along the Sabarmati River, Xi dressed in a Nehru jacket. Left largely unspoken, though, are the deep worries in India over Chinese maneuvering in the Indian Ocean, where New Delhi's years of dominance is being chipped away by billions of dollars in aid from Beijing and gargantuan Chinese construction projects. And while China's recent push for dominance in the South China and East China seas get more attention, the quiet contest for influence in the Indian Ocean is being watched carefully from Tokyo to Washington, D.C. More than anything else, the worries are over energy.
