The Globe and Mail reports in its Tuesday edition that India-based JSW Steel's discussions with Teck Resources over buying a possible share of its coking coal unit have yielded "nothing concrete," JSW Steel chief executive officer Jayant Acharya said Monday. A Reuters dispatch to The Globe says that last month, JSW Steel, India's largest steelmaker by capacity, had slowed the buying process because of a diplomatic spat between New Delhi and Canada. "There is nothing concrete on Teck. We are in discussion with strategic possibilities among which Teck is one," Mr. Acharya told Reuters. Ties between India and Canada deteriorated after New Delhi and Ottawa expelled each other's diplomats in the wake of the murder of a Sikh separatist activist in British Columbia in June. India's government considered him a terrorist. Mr. Acharya said the diplomatic row should not affect business decisions, adding, "Let us see how those situations evolve." Mr. Acharya said the company was exploring overseas coal assets in different countries, including Australia. He further said an increase in prices of coking coal, used in steelmaking, in the past six weeks would affect costs during October through December unless they moderated.
