Under the requirements of the State-owned Assets Supervision and Administration Commission of the State Council, China’s three leading telecom carriers, China Telecom, China Mobile and China Unicom, will slash marketing expenses to the tune of over 40 billion yuan (US$6.5 billion) over the next three years, which might slow the popularity of 4G services in China. China Mobile will see the largest cut, at 24 billion yuan (US$3.9 billion). The belt-tightening move will put a damper on the subsidies provided by the three carriers for purchase of mobile phones by their subscribers, as a result of which mobile-phone subsidies by the trio will drop by 10 billion yuan (US$1.6 billion) this year, including 5 billion yuan (US$807 million) for China Mobile and 2.5 billion yuan (US$403 million) each for China Telecom and China Unicom, according to Shanghai’s National Business Daily.
