While the dispute between Russia and the US over the conflict in Syria is likely to overshadow the two-day summit starting tomorrow in the Russian city, splits between emerging markets and the US over Federal Reserve's winding down of stimulus and the slowing growth of India and other four BRICS countries are expected to remain in focus.
In a statement before leaving for the Summit, Singh called for an "orderly exit" from unconventional monetary policies being pursued by the developed world for the last few years to avoid damaging growth prospects of the developing world.
Singh, who has attended all the previous G20 summits since the first meet in Washington in 2008, is due to return home on Saturday evening.
