New Delhi, July 30 (IANS) Prime Minister Narendra Modi’s visit to Nepal next month is expected to boost cooperation in hydropower and infrastructure sectors between India and the Himalayan nation, said observers here even as visiting Nepalese Commerce Minister Sunil Bahadur Thapa Wednesday expressed his country’s keenness to learn from Modi’s development model. “Nepal is more like an elder sister to India than a younger brother. We share a common terrain in southern Himalayas, as well as deep familial, cultural and civilizational bonds,” Jayant Prasad, former ambassador of India to Nepal, said at a discussion here on “India-Nepal Ties: Energising the Future” organised by the Ananta Aspen Centre, a not-for-profit organisation.
