The agreement provides for exchanging news materials in English, as well as carrying out joint media projects aimed at strengthening relations between the two countries.
"India is one of our long-standing strategic partners and we pay close attention to the strengthening of ties with the leading players in the Indian media market. I'm sure that our mutual work with UNI both in information exchange and joint projects will be mutually beneficial and fruitful", said Sergei Kochetkov.
Commenting on the pact, the United News of India chief, Mr Ashok Uphadyay, said it was in accordance with the agency's oft-stated desire and campaign against the monopoly of the flow of news by Western agencies. He recalled UNI's long-standing and warm relations with Russian media.
"The ties, the veteran journalist affirmed, would continue to grow and flourish until there were true democratisation and removal of Western bias in the flow of international news".
The agreement with UNI is Sputnik's third partnership with Indian media.
