Lenovo Group is reportedly bidding for acquiring Brazil's largest PC maker Positivo Informatica, which may be the largest overseas acquisition by the Chinese champion PC maker since it bought IBM's PC arm in 2005.

The deal, if successful, could help Lenovo speed up its expansion in the emerging market at a time when the PC markets in major developed countries are slwoing due to the financial crisis.

Executives of Lenovo have visited the headquarters of Positivo Informatica in the southern city of Curitiba and showed great interest in buying out the company, reported local media Estado de S. Paulo.
