According to Reuters, the nations agreed to a new deal which would limit the liability risks US suppliers would face with building nuclear reactors in India and which resolved US concerns on “on tracking the whereabouts of material supplied to the country”

"Ultimately it's up to the companies to go forward, but the two governments came to an understanding," US ambassador to India Richard Verma said.

India Prime Minister Narendra Modi also made comments on emissions reduction during the carbon-fearing US President’s tour.

While no emissions deal was struck, Bloomberg praised Modi for saying India, along with other nations, has an obligation to reduce fossil fuel emissions. “The remarks represent a shift in India’s tone on global warming,” it commented.

“It previously emphasised the historical responsibility of industrial nations for creating the problem, and the Indian government has been ambiguous about whether it will adopt domestic targets for reducing greenhouse gases.

“Modi’s comments suggest he’s ready to work with Obama on a deal in Paris in December that would for the first time require all nations, rich and poor alike, to restrain emissions.”

While blackout-prone India is yet to commit to emission targets, Obama does leave the country with news of a solar energy win with Modi’s government seeking $100 billion of investment over seven years to lift solar power capacity 33 times to 100,000 megawatts.

"We very much support India’s ambitious goal for solar energy, and stand ready to speed this expansion with additional financing," Obama said on the first day of the three-day trip that ended yesterday.

The trip also covered issues around more traditional energy sources.

According to a CEO Forum covered by India Today, Oil and Natural Gas Corp chairman and managing director Dinesh K Sarraf talked about the challenges faced to import US LNG due to the absence of a free trade agreement between the two nations.

“India is seeking long term assured supply of natural gas from the US at competitive prices to meet its energy needs but Washington bars sale of LNG to nations with which it does not have FTA,” the newspaper reported.

Modi’s Indian press coverage during the tour was less favourable, arguably due to his decision to wear a suit with pinstripes which on closer inspection were actually his name “Narendra Damodardas Modi” vertically embroided in gold thread over and over again.

“Narcissism, thy name is @NarendraModi,” was a popular tweet comment.
