New Delhi also expressed concern over developed countries stand on the overall package of the 33-member WTO meeting here saying on a few issues the rich nations are paying only "lip service".
India recently adopted an ambitious food security scheme guaranteeing highly subsidised foodgrains to two-thirds of its population, a programme that cannot be implemented if the current subsidy levels set by WTO for the country are accepted.
India will not compromise its farmers' interest or succumb to mercantilist ambitions of rich nations, he said.
There is a national consensus and complete political unanimity on this matter in India, Sharma said, adding: "It is therefore difficult for us to accept an interim solution as it has been currently designed.
"We can no longer allow the interests of our farmers to be compromised at the altar of mercantilist ambitions of the rich. The Bali Ministerial Meeting is an opportunity for the developing countries to stay united in resolve to demonstrate the centrality of agriculture in trade talks."
