(Telecompaper) Indian mobile operator Bharti Airtel is in talks to merge its Sri Lanka unit into Dialog Axiata. The transactions involves a share-swap deal, ET reports, citing two unnamed people familiar with the matter. A potential Airtel Lanka-Dialog Axiata merger will be similar to the recent merger of Bharti Airtel and Axiata's telecom units in Bangladesh. Axiata will be the dominant shareholder and Airtel a strategic minority holder in the combined entity, the same sources added.
