India and Russia on Saturday signed billions of dollars of defence and energy deals including purchase of missile systems, frigates and joint production of helicopters, at a key conference being held in the western seaside state of Goa.

Goa is hosting a two-day BRICS (Brazil, Russia, India, China and South Africa) summit.

Prime Minister Narendra Modi and Russian President Vladimir Putin held wide-ranging talks covering the entire expanse of bilateral engagement following which the two sides signed a total of 16 MoUs and made three announcements to boost ties in sectors such as trade and investment, hydrocarbons, space and smart cities, according to PTI.

The two leaders also dedicated unit two of the Kudankulum nuclear power plant and witnessed the foundation laying of its Unit 3 and 4, it stated.

The defence deals included India buying the ‘gamechanger’ S-400 Triumf air defence system from Russia at a cost of over $5 billion. The two countries will also collaborate in making four state-of-the-art frigates, besides setting up a joint production facility for Kamov helicopters, said the report.

Reading out a statement to the media in the presence of Putin, the Prime Minister appreciated Russia’s understanding and support of India’s actions to fight cross-border terrorism, an oblique reference to India’s surgical strike across the LoC targeting terror launch pads.

“Russia’s clear stand on the need to combat terrorism mirrors our own. We deeply appreciate Russia’s understanding and support of our actions to fight cross-border terrorism, that threatens our entire region.

“We both affirmed the need for zero tolerance in dealing with terrorists and their supporters,” Modi said.

Putin, on his part, said both countries have close cooperation in fighting terrorism.

Modi said the “highly productive” outcomes of the meeting clearly establish the special and privileged nature of strategic partnership between the two countries.

“They also lay the foundations for deeper defence and economic ties in the years ahead. The agreements on manufacturing of Kamov 226T helicopters; constructions of frigates; and acquisition and building of other defence platforms are in synergy with India’s technology and security priorities,” he said.

The two sides signed an Inter Governmental Agreement for the purchase of the S-400 ‘Triumf’ long-range air defence missile system, which can destroy incoming hostile aircraft, missiles and even drones at a range of up to 400 km.

Another important deal is for four Admiral Grigorovich-class (Project 11356) guided-missile stealth frigates.
