Russia, India set to sign $5 billion arms deal

New Delhi CNN  — 

India could soon be faced with the threat of US sanctions following a controversial $5 billion weapons deal with Russia, a move analysts say poses more of a headache for Washington than it does Delhi.

Indian Prime Minister Narendra Modi finalized the deal, which will see India take possession of a high-tech S-400 missile defense system, during a bilateral meeting with Russian President Vladimir Putin in the Indian capital New Delhi on Friday.

The deal could potentially open India up to US sanctions under legislation known as Countering America’s Adversaries Through Sanctions Act (CAATSA).

The law, signed by President Donald Trump last August, is designed to punish Moscow for its “malign activities.” Last month, the US imposed sanctions against China for its purchases of Russian military equipment, including the S-400, under CAATSA legislation.

But whereas China is an emerging rival power, India is seen as an important US strategic ally.

US defense chiefs have worked hard to increase cooperation with Delhi in a range of areas in recent years, amid shared concerns over Chinese military expansion in the Indo-Pacific region.

India’s purchasing of the Russian weapons system effectively forces the Trump administration to choose between punishing Delhi – and destroy the fledgling defense relationship – or granting the country an exemption, weakening the effect of the sanctions and opening up the US to accusations of favoritism.

Following the completion of the deal Friday, the US embassy in Delhi told CNN that CAATSA legislation was not intended to “impose damage to the military capabilities of our allies or partners.”

Asked whether the India-Russia deal would qualify for a potential exemption, the spokesperson said the embassy was unable to “prejudge any sanctions decisions.”

“There are strict criteria for considering a waiver,” said the spokesperson, adding that waivers would be considered on a “transaction-by-transaction basis.”

Speaking to CNN, Peter Layton, from Australia’s Griffith Asia Institute, said the problem for the US is that if it allows India to purchase the S-400 there is no reason why it should not also allow other countries, such as Turkey to do so too.

“The CAATSA will appear a rather subjective sanction program if it only applies to some nations and not all,” said Layton.

What is the S-400 Triumf?

India and Russia have been in talks over the purchase of the S-400 since 2015.

The high-tech system is considered the most effective surface-to-air system in its class, surpassing the capabilities of the aging US Patriot missile system, according to experts.

It can engage targets, including manned and unmanned aircraft, cruise missile and ballistic missiles at a range of up to 400 kilometers, while remaining beyond the reach of standard radar jamming equipment.

“The S-400 being so capable and at a relatively affordable price is hard for US arms manufacturers to compete against,” said Layton, who described the missile system as offering superior value-for-money to comparable US options.

Unsurprisingly the S-400 is a big export priority for Russia. Friday’s deal with India follows a similar deal with Turkey, which despite being a NATO ally, signed a provisional agreement to buy the Russian-made system in December.

The Turkey deal has caused consternation in Washington, where a bipartisan group of lawmakers have attempted to block the transfer of the US’ F-35 Joint Strike Fighters to Turkey, citing security concerns.

US defense officials believe once operational, the S-400 could be used to gather technical data on US designed fighter planes and that critical information could be passed to Moscow either intentionally or unintentionally through a back door in the Russian designed system.

India’s purchase of the S-400 may result in the US refusing to sell “advanced fighter aircraft types” to Delhi in the future, said Layton.

“It is important to note that other parts of the US-India relationship would not be impacted, simply the sale of advanced military aircraft,” added Layton.
