China’s Lenovo said on Thursday that its acquisition of IBM’s personal computer business will be successfully completed in the nearest future, even though the deal is now investigated by the security forces.

The Committee on Foreign Investments in the United States (CFIUS) that deals with corporate acquisitions by foreigners on Tuesday voiced some concerns on the impact of the deal on national security.

The authorities now take an interest in whether the deal that will offer the Chinese maker a foothold in the US, such as IBM’s research facilities in North Carolina, that can be used as platform for industrial espionage.

This week the committee will decide on the prospects of opening a formal investigation.

In 2003 the committee blocked another US-Chinese deal refusing to approve the sale of Global Crossing telecommunications network to Hong Kong-based Hutchison Whampoa.

Lenovo CEO Yang Yuanqing said that the US Administration has not informed the Chinese PC maker that there are obstacles to the deal.

“The acquisition is proceeding as normal,” Mr Yang said.

The $1.75 billion deal if completed will become the largest overseas acquisition by a Chinese company and has already been described as a sign of China’s emerging economic power.
