The move is aimed at strongly presenting the views of developing countries at the forthcoming ministerial meeting in Nairobi, scheduled in December.
During Prime Minister Narendra Modi's visit to China in May, the two countries had decided to have a special mechanism to discuss issues at the World Trade Organization (WTO) talks as they have similar views on many issues.
"India and China are jointly coordinating on WTO issues. It will help in putting forward the views of developing countries in the Nairobi meeting," the official said, adding the group would meet shortly to discuss all the issues which are of interest to developing countries.
Besides food security, the other issues of common interest to India and China include a cut in agri-subsidies by the developed nations.

India, the official said, wants that all issues including Doha Round matters, should be taken up in the Nairobi meeting as "cherry picking of issues" would not help the multi-lateral body.
India wants to bring back issues related to the long-stalled Doha round including agriculture such as export subsidies, cotton and fishery subsidies and market access.
