Strong performance in these markets helped push Lenovo's overall sales up 50 percent over the same period last year, to US$5.1 billion. The company, China's largest PC maker, reported a quarterly profit of $55 million compared to a loss of $16 million one year ago.

While China and emerging markets provided most of the growth, Lenovo also did well in mature markets, where sales rose 39 percent, to $1.8 billion. Sales in China and emerging markets were $2.5 billion and $821 million, respectively, during the quarter.

Describing the company's financial results as "excellent," Lenovo Chairman Liu Chuanzhi said the company's decision to focus on China and fast-growing emerging markets was paying off.

"Our performance was strong globally, Lenovo has a clear strategy when and where to focus on gaining share, and when and where to focus on maximizing profit, and we executed that strategy well," Liu said in a statement.

"Despite the ongoing challenges and uncertainties of the world's economy, I firmly believe that Lenovo's future is bright," he said.
