- India, Russia close Rs 40,000 crore deal for S-400 Triumf missiles
- Deal likely to be announced before PM Modi-Vladimir Putin October summit
- Efforts on to insulate deal from US sanctions against Russia: Officials
They said the two countries are now trying to find a way out to evade the provisions of a US law that seeks to punish countries and entities engaged in transactions with the defence or intelligence establishment of Russia.
"The negotiations for the missile deal have been concluded. The financial component has been finalised," a top official involved in the negotiations for the deal with Russia told PTI.
The official said both Russia and India are likely to announce the deal before an annual summit between Prime Minister Narendra Modi and Russian President Vladimir Putin in October.
Two other officials said both sides are now looking at ways to insulate the deal from the sanctions announced by the US against Russia under its Countering America's Adversaries Through Sanctions Act (CAATSA).
The issue is understood to have figured during PM Modi's informal talks with Vladimir Putin in Sochi last week.
The US had announced sanctions against Russia under the stringent law for its alleged meddling in the American presidential election in 2016.
US Defence Secretary Jim Mattis last month appealed to the Congress to urgently provide India the national security waiver, saying imposing sanctions under CAATSA for the S-400 air defence missile deal would only hit the US.
India wants to procure the long-range missile systems to tighten its air defence mechanism, particularly along the nearly 4,000-km-long India-China border.
In 2016, India and Russia had signed an agreement on the 'Triumf' interceptor-based missile system which can destroy incoming hostile aircraft, missiles and even drones at ranges of up to 400 km. S-400 is known as Russia's most advanced long-range surface-to-air missile defence system.
China was the first foreign buyer to seal a government-to-government deal with Russia in 2014 to procure the lethal missile system and Moscow has already started delivery of unknown number of the S-400 missile systems to Beijing.
The S-400 is an upgraded version of the S-300 systems. The missile system, manufactured by Almaz-Antey, has been in service in Russia since 2007.
