Prime Minister Sheikh Hasina's visit to Delhi over the weekend highlights the deepening bilateral relationship with Dhaka and also its important structural consequence growing interdependence with Bangladesh. India's foreign policy can claim great success for the former relations with Bangladesh have never been as good as they are today. They are also the best when viewed in comparison with our other neighbours. But India's economic policy makers can be rather insensitive to the logic of interdependence. Hasina's visit saw agreements on expanding connectivity and transit, easing travel across the border, strengthening trade and investment ties, boosting development cooperation, putting the fledgling defence cooperation on a firmer basis and promoting regional cooperation. Even as Delhi celebrates the golden age in the relationship with Dhaka, however, it must heed some important warning signs. That Hasina publicly complained, albeit in a light hearted manner, about the impact of India's recent move to ban onion exports on her kitchen, underlines the headaches in the neighbourhood that Delhi's economic decisions generate. Hasina was not objecting to the decision itself that has produced immediate onion shortages in Bangladesh. She was pointing to its sudden and unilateral nature. If Delhi had informed Dhaka in advance, Hasina said, her government could have made alternative arrangements for onion import. The problem goes deeper and reveals a lingering autarkic and anti-market orientation in Delhi's economic policy even as India's national strategy calls for regional integration.
