Proposed purchases by China's Lenovo Group of IBM's low-end server unit and Google's Motorola Mobility business should be completed by year-end, Lenovo Chief Executive Officer Yang Yuanqing said on Wednesday.
The deals are currently undergoing approval by US and Chinese regulators.
"Both deals are under the approval process in the two countries and they are progressing," Yang said at Lenovo's annual general meeting in Hong Kong.
"We hope to complete the two deals by year-end," he said. "The US government...and US Army are all our clients. There has been no issue and we will keep this tradition."
Last week, the Wall Street Journal reported that the US$2.3 billion IBM deal was in limbo while the US government investigated national security issues.
The January announcement for the acquisition came nearly a decade after Lenovo bought IBM's money-losing ThinkPad business for US$1.75 billion, which had also faced scrutiny.
Tensions between the United States and China over cybersecurity issues have reached new highs since the US Department of Justice charged five Chinese military officials with hacking the systems of US companies to steal trade secrets in May. China denies the charges and has in turn accused Washington of massive cyberspying.
