Yang Yuanqing, chairman of the board of Lenovo Group, estimates that Lenovo will purchase CNY1.2 billion worth of operating system from Microsoft for its China market, and a total of CNY10 billion for the global market this year.

Yang said the large outsourcing volume was a milestone in the China-US economic cooperation and it also showed Chinese enterprises' strong determination in respecting and protecting intellectual property rights.

Since last November, Lenovo has begun to pre-install Microsoft's Windows operation system on its PCs. According to Yang, this measure is very effective in countering piracy and within a two months after it was adopted, the company sold 600,000 operating systems of Microsoft.
