The WTO's trade facilitation agreement too would help reduce time and cost for traders.
Briefing reporters on the initiatives taken by her ministry during the last two years, Sitharaman said India took a firm stand in the WTO's Nairobi meet to safeguard the interests of farmers.
Level playing field has been obtained for farmers. They were at disadvantage because of the export subsidies given by many developed countries and after Nairobi "we have achieved the goal", she said.
"Advanced countries will have to withdraw every subsidy that they were providing and therefore India's farmers now stand a better chance competing internationally and...Enjoy a level playing field," she said.
On the Doha Development Agenda, Sitharaman said India completely reinforced and insisted that all the leftover agenda including reduction of overall subsidies by the developed countries should be fulfilled.
She also said there is "absolutely" no threat for India to provide minimum support price to farmers.
