Russian President Dmitry Medvedev and Indian Prime Minister Manmohan Singh held unofficial negotiations at Medvedev’s countryside residence on Sunday.

Any Russian visit of the Indian prime minister “is a major event, and that is why I wanted to meet you in both official and unofficial formats,” Medvedev said.

Singh said the unofficial meeting was a privilege, and India-Russia relations were boosted in the office of President Medvedev.

He also said that relations with Russia were the most important for India.

The brief conversation developed into an informal dinner.

Russian and Indian delegations will hold official negotiations at the Kremlin on Monday.

Medvedev and Singh will sign a joint declaration, the Kremlin told Itar-Tass.

“This document will evaluate the significance of Russian-Indian strategic partnership and common vision of the formation of a poly-centric international system in the 21st century,” the Kremlin said.

Besides, the delegations will sign a number of intergovernmental and interdepartmental agreements.
