And in the best interest of all stakeholders," Nath told Sarin who arrived here early this morning to pursue the acquisition of India's fourth largest mobile venture.Sarin told reporters after the meeting the talks were "fruitful" and that "formal bidding was still a few weeks away." When asked whether that meant the bids would come by the end of this month, he said: "Later than that."On whether he sought clarifications from Nath on FDI regulations in India, Sarin said: "Regulations are clear."Sarin had met Bharti Airtel chief Sunil Mittal in the morning. Mittal, speaking to mediapersons, said the issue of Vodafone divesting its nearly 10% stake in Bharti is "at a preliminary" stage, and refused to comment on the issues discussed.Sarin, told PTI on his arrival that Vodafone was looking to buy whatever stake is available in Hutch-Essar and put in a bid in the next few weeks.Hutch-Essar, the country's fourth largest mobile player, is 67% owned by Hong Kong-based Hutchison Telecommunications International and 33% by Essar.Meanwhile, Communications Minister Dayanidhi Maran, ahead of his scheduled meeting with Vodafone CEO Arun Sarin, said the government wanted good companies to enter the country."We want good players to come to India. Whatever they do (thereafter) is their business," he told PTI while commenting on the interest generated by the country's telecom sector.Without mentioning Vodafone's bid for Hutch-Essar, he said: "The recent development (of foreign players interest in acquiring Indian firms) shows the strength of India's telecom sector and proves that the sector is growing. It also proves that we made the right decision in increasing FDI cap to 74% per cent." He said the FDI policy for the telecom sector was "a clear signal" to the foreign players about the growth and opportunities in the Indian telecom market.
