JSW Steel Ltd's discussions with Canada's Teck Resources over buying a stake in its coking coal unit have yielded 'nothing concrete', according to JSW Steel Chief Executive Jayant Acharya. The process had slowed due to a diplomatic spat between India and Canada. Acharya stated that the company is exploring overseas coal assets in different countries, including Australia. The company reported a Q2 profit last week, helped by robust domestic demand and lower input costs.
