The United States and Japan have raised concerns at the World Trade Organisation (WTO) about India's frequent bans on onion exports, which they say are imposed without prior notice and put importing countries in a difficult position. They have asked India to explain its actions and why it has not opted for an export quota. The countries have also questioned India's impact on the food security of importing members and why it has chosen export bans over export quotas. Meanwhile, Serbia has opened its market for Indian potatoes, onions, and pomegranates. India has a history of imposing export restrictions on onions annually in winter due to potential crop damage from unseasonal rains.
