The leaders of the Shanghai Cooperation Organization (SCO) agreed on Friday to take steps to increase the use of national currencies in trade between their countries, according to a joint declaration adopted on Friday.
The group - which comprises China, India, Russia and Pakistan alongside four Central Asian states - said "interested SCO member states" had agreed a "roadmap for the gradual increase in the share of national currencies in mutual settlements", and called for an expansion of the practice.
No further details were provided and the group did not say who the "interested states" were.
Moscow is seen as the main driver of the push towards national currencies as it tries to reduce its reliance on the US dollar and other Western currencies for trade following the imposition of sweeping new Western sanctions.
Last week, the Russian gas producer Gazprom said China would pay for half its Russian gas supplies in rubles and half in Chinese yuan. Previous contracts have been denominated in euros or dollars, the dominant reference currency for global oil trade.
Leading oil producer Iran, like Russia subject to broad international economic and financial sanctions, is also on the verge of joining the SCO.
