China Telecom said Wednesday net profit in the first six months of the year rose 15.9 percent year-on-year, citing growth in its 3G mobile operation. The country\'s largest fixed-line operator by subscribers posted unaudited profit of 10.21 billion yuan ($1.67 billion) for the first half, compared with 8.81 billion yuan for the same period last year. Revenue jumped 14.1 percent to 157.52 billion yuan, the company said in a filing to the Hong Kong stock exchange. But it decided not to pay an interim dividend, citing uncertainties over domestic regulatory policies and plans to speed up the expansion of its 3G services. The number of 3G subscribers in the first half jumped 26.5 percent, or 18.28 million, to 87.33 million. \"The Board of Directors has decided not to pay an interim dividend this year in order to maintain adequate funding flexibility,\" Wang Xiaochu, the telecom giant\'s chairman and chief executive officer, said in the filing. \"In the second half of the year, we will firmly seize the present golden window of opportunity and focus on accelerating the scale expansion of our strategic 3G services and wireline broadband services.\" Hong Kong-listed shares in the company ended 1.0 percent higher at HK$4.06 Wednesdasy, while the broader market closed down 0.69 percent.
