Russia plans to deliver S-400 surface-to-air missile systems to India on schedule, President Vladimir Putin had said on Thursday.

India had agreed to buy the S-400 missile system from Russia last year despite US warnings the purchase could trigger sanctions against it.

India said that it needed the weapons to bolster its defences against China.

"As far as the S-400 deliveries are concerned, everything is going according to plan. Our Indian colleagues have not asked to speed anything up, it`s all going fine," President Putin told reporters at a summit of BRICS countries in Brazil.

Russian President also told reporters that he had discussed supplying Russian S-400 missile defence system to India with Prime Minister Narendra Modi.

PM Modi and President Putin also reviewed the progress made in the bilateral relationship between India and Russia since the former's visit to Vladivostok in September.

"I had an excellent meeting with President Putin. During our talks, we reviewed the full range of India-Russia relations. India and Russia are cooperating extensively in areas such as trade, security and culture. People of our nations will benefit due to close bilateral ties," the Prime Minister said.

The two leaders met over two months after holding extensive talks in Russia`s Far East city of Vladivostok on the sidelines of the Eastern Economic Forum (EEF) wherein India had announced an "unprecedented" USD 1 billion line of credit to develop the country`s resource-rich Far East region.
