Acer China has formally opened its offices in Shanghai this week, indicating the beginning of a battle with Dell and Lenovo in sales of electronics and computers.

Since April 1, 2005, Acer has been reorganizing its activities in China to temper declining sales.

Acer has re-classified and split its total China Market into respective Taiwan Market and Mainland Market areas. It has also transferred the original general manager of Mainland Acer to Taiwan and moved the so-called "Godfather" of Acer, Lan Taiyue, to the Mainland's offices.
