Thai telco TOT has revealed that the US government has expressed an interest in investing in the incumbent fixed line operator’s touted 3G mobile network rollout through its Thai Mobile subsidiary. TOT’s director Nalikatibhag Sangsnit said that the US Trade Representative informed the state-run firm of the interest in the planned project, which is thought to require funding of between THB14-17 billion (USD450-545 million). Previously TOT revealed that the governments of China and Japan had expressed interest in the project. TOT is currently preparing to present its 3G plans to the Information and Communication Technology Ministry for approval. Minor GSM operator Thai Mobile is the country’s only holder of UMTS spectrum; TOT recently reached a long-delayed agreement to buy out sister company CAT Telecom’s stake in Thai Mobile and take full control of the struggling venture.
