Russian President Vladimir Putin has already decided that he will be a virtual participant.

China and Russia are keen to discuss expansion of BRICS at the summit, while India has reservations about that idea.

Relations between New Delhi and Beijing nosedived after a clash on their disputed Himalayan border in 2020 in which 20 Indian soldiers and four Chinese soldiers were killed.

The SCO summit was held days after Modi returned from a state visit to Washington where President Joe Biden rolled out the red carpet for him.
