Barack Obama and Indian Prime Minister Narendra Modi showed a close Sunday complicity in New Delhi, highlighting a step forward in cooperation on civilian nuclear energy at the start of a three-day visit of US President India.

The day, which began with a frank hug at the airport where Obama was greeted by Indian Prime Minister, continued with a meeting of several hours punctuated by a joint press conference with the decidedly positive tone.

If, apart from advanced civilian nuclear, this meeting did not result in any major announcement, Mr. Modi said the powerful symbol that represented the visit of Mr. Obama, four months after their first meeting at the House Blanche.

“Relations between countries depend little dots and commas (a document), but much of relations between their leaders, the chemistry between them,” argued the Indian Prime Minister. “Barack and I have developed a real friendship,” he added, noting that it would help to bring “Washington and New Delhi, but also the peoples of both countries.”

The agreement between the two marks an inflection relations between the two countries, which had deteriorated in late 2013 because of diplomatic wrangling.

In addition, for a decade, the United States had had no contact with Modi, who was denied a visa in 2005 because of anti-Muslim riots that bloodied the state of Gujarat in 2002 he led.

First realization of this new impetus, the two leaders announced the relaunch of their cooperation on civil nuclear blocked for six years, while remaining coy about the exact scope of the agreement.

“I am pleased to announce that six years after the signing of our bilateral agreement, we are moving to a compatible business cooperation with our laws and international legal obligations,” said Mr Modi.

The agreement signed in 2008 was at a standstill due to the Indian law which provides that manufacturers of nuclear power plants are responsible in case of an accident , a term considered too heavy by the bulk of foreign nuclear groups.

India proposed the establishment of a “pool of insurers’ which allow manufacturers and individual insurers not bear a disproportionate cost.

“This opens the way for US groups and others to move forward and help India develop nuclear energy,” said Richard Verma, the Ambassador of the United States in India.

Strengthening economic cooperation appears as the central issue of this visit. Trade between the two giants have almost quintupled since 2000 and now stands at $ 100 billion per year. The stated objective not Washington is to multiply again this figure by five over the coming years.
