I disagree. It is economics because even though we granted MFN a decade back, you guys did not capitalize on it because your manufacturing costs are high relative to India.
Our agriculture is highly subsidized to benefit our farmers. We spend close to $100 billion on agricultural subsidies and provide free electricity to farmers. Income from agriculture is exempt from taxes. IF you grant MFN you are afraid that we will flood your mandi with our cheaper agri products.
If you import our agri products duty free then your consumers will benefit by reduced prices by up to 30%.
