New Delhi, Dec 23 (IANS): Prime Minister Narendra Modi on Wednesday said that he is "very optimistic" about his visit to Russia for talks with Russian President Vladimir Putin.

"Today I will commence my visit to Russia, my first bilateral visit after we formed the Government. I am very optimistic about the outcome of this visit," Modi said in a Facebook post.

On Wednesday, Modi leaves for Moscow where he will attend the 16th India-Russia annual summit meeting during which a number of bilateral agreements are expected to be signed, with trade being a major focus area.
