The executive also notes that revenue sharing is literally a foreign concept. "Secondly," he says, "our business model does not entail sharing revenue with terminal producers -- we don't share revenue. That's a Chinese rule. All it is right now, on the iPhone and Apple, is that the firm welcomes their approach." Li Zhengmao, the executive director of China's other wireless carrier, China Unicorn, says that his company does not have any plans to bring the iPhone to the country. "But of course," he cautions, "we're always willing to discuss a good business opportunity if it presents itself." Zhengmao argues that the iPhone will succeed in China so long as it has Mandarin text messaging; Gartner analyst Sandy Shen, however, believes that China Mobile will strongly resist any attempts at enforcing revenue sharing, and that for most Chinese, a legal iPhone will be far too expensive. The iPhone costs an average of $500, but in China, this equates to twice the average worker's monthly salary. At present, there is not even a Chinese version of the iTunes Store, Shen comments.
