India, Russia likely to ink S-400 Triumf deal before Modi-Putin summit

Countering America's Adversaries Through Sanctions Act (CAATSA), which came into effect in January this year, mandates the Donald Trump administration to punish entities engaging in significant transaction with the defence or intelligence establishment of Russia.
US Defence Secretary Jim Mattis last week 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 Sino-India border.
