Shares in Chinese hardware companies plunged on Friday led by computer maker Lenovo, after a report on Thursday evening claimed that spies had used thousands of microchips to infiltrate the IT systems of US companies.
Bloomberg claimed there had been a major "supply chain hack" of around 30 companies as well as US government agencies by the Chinese People's Liberation Army.
The news agency said Chinese spies had placed the malicious computer chips in the hardware used to make servers in the US.
It claimed that Amazon and Apple were among the companies affected, and were cooperating with a wider US government investigation into the chips, led by the FBI.Both Apple and Amazon denied the report.
However, the report caused ripples across Asia, with shares in a number of Chinese hardware companies slipping over the course of Friday.
Hong Kong-listed telecommunications company ZTE closed down 11 per cent yesterday and computer maker Lenovo ended 15 per cent lower, as analysts warned the allegations may dampen demand for Chinese-manufactured goods.
