DUBAI (AFP) - Emirates Telecommunications Corp (Etisalat) said on Saturday it has bought Tigo Sri Lanka , a unit of Millicom International Cellular, for 207 million dollars amid growth opportunities in the southeast Asian country. Tigo Sri Lanka , the second-largest mobile phone operator in Sri Lanka , has a market share of 21 percent. By September 2009, it had 2.25 million subscribers, Etisalat said. Both Sri Lanka as a country and Tigo Sri Lanka as a company provide opportunities for further growth, Etisalat said. Standard Chartered Bank acted as financial advisor to Etisalat for the acquisition. Etisalat already has existing investments in Asia including Pakistan, Afghanistan, Indonesia and India, markets which are among the worlds fastest growing in the telecommunications sector.
