While visiting with India's top leaders in India this week, Hillary Clinton is expected to sign a deal allowing U.S. companies the exclusive rights to sell nuclear power plants—an agreement that could be worth $10 billion to U.S. sellers. "We want to broaden and deepen our strategic understanding," the secretary of state told an audience at Delhi University. Despite efforts by both countries to sure up relations—two-way trade has doubled in the last five years, for instance—one sticking point remains India's refusal to accept binding limits on carbon emissions. "This is part of a negotiation," Clinton said. "It's part of a give-and-take and it's multilateral, which makes it even more complex. But until proven otherwise, I'm going to continue to speak out in favor of every country doing its part to deal with the challenge of global climate change."
