China will become the world's biggest computer market within three years, overtaking the US, Bloomberg reported, citing Acer Inc's Chief Executive Officer Gianfranco Lanci.

"We see China as huge potential," Lanci said at a press conference in the western city of Chongqing. Acer, the world's second-largest computer maker behind Hewlett-Packard Co, is aiming for the No 2 slot in the Chinese market, he said.

Computer sales in China, the world's fastest-growing major economy, may rise 21 percent this year from last year's 54 million units, according to IDC. That is faster than the 14 percent gain in global shipments, the research company said.

Acer overtaking the Chinese market leader Lenovo Group Ltd in its home seems "impossible," Lanci said. The Taipei-based company is currently ranked sixth in China with a third-quarter market share of 4.3 percent, while Lenovo had 28.8 percent, according to IDC.

"We never said we want to be number one in China," Lanci said. "We want to become number two in China, and we are almost number two. That is much more achievable."

Globally, Acer aims to displace HP from the top spot, he said, reiterating a target the company set previously.

Lanci was in Chongqing to sign agreements with the municipal government related to a $150 million investment in a distribution center in the city that was announced last month.
