Tata Steel's $7.7 billion acquisition of the London-based Corus Group may be the largest foreign deal by an Indian company, the conglomerate, however, is not about to rest on its laurels, so to speak.The group plans to expand its growth into countries in Africa, East Asia and Latin America, its chairman Ratan N Tata has said.In an interview with New York Times in London on Friday, Tata said the company's next moves include some far-flung markets.The Tata Group, the parent of Tata Steel, is looking to expand in Vietnam, Indonesia, South Africa, Brazil, Argentina and Uruguay, he said. Tata invests in countries where "we can make our presence felt," where the company already has products that fit the needs of the country or the market has been too small to attract other global conglomerates, the 68-year-old chairman of the Tata Group said. "We're not just blindly growing turnover and growing scale." With the deal, Tata, until now the 55th largest steel maker in the world, will become the fifth largest. The Tata Group also owns auto manufacturing, consumer goods, energy and technology companies around the world.Tata is paying 455 pence a share for Corus. Tata said his company had spent a long time weighing the deal. "What we have today is the evolution of almost a year of discussions," he said.He ultimately decided to do the deal because he had been impressed by the similarities in management at both companies, and by Corus's turnaround in recent years.
