KOLKATA: West Bengal is one of the top Indian states on the 'ease of doing business matrix today' said Mukesh Ambani , chairman of Reliance Industries on Friday.He was speaking at the Bengal global business summit in Kolkata.'I have no doubt in recommending West Bengal as a top investment destination to my friends in India and overseas based in Reliance's own first hand experience in terms of ease of doing business in the state,' said Ambani in the presence of a beaming West Bengal CM Mamata Banerjee According to him, Reliance had become one of the top employers in West Bengal with some 11,000 direct employees and over 30,000 indirect staffers, largely due to the ease of doing business in the state and 'culture of fast track clearances'.Reliance's telecom arm, Reliance Jio Infocomm , he said, had already invested over Rs 5000 crore in the state and would take it the next level in coming months. Ambani, however, did not reveal fresh investment numbers.He said Reliance Jio had already connected 1059 towns and 24339 villages to its high speed 4G network, and assured the state chief minister that all 40,000 villages would be plugged into Jio's high speed internet network by end-2017.Ambani said in the coming months, Reliance Jio would connect all urban and rural schools, the 2000-plus colleges, hospitals and healthcare centres in the state to its high speed internet network to boost broadband penetration.He said Jio would also partner with small entrepreneurs in the state.Last month, Reliance Jio launched its 4G services for group employees and the much awaited commercial launch is likely in the next three to four months.
