A White House-led review of security risks posed by Chinese telecom firm Huawei Technologies found no clear evidence that the company had spied for China, Reuters reported, citing two people familiar with the probe. However, the review concluded that Huawei’s systems were potentially vulnerable to hacking. The White House inquiry asked detailed questions of nearly 1,000 telecom equipment buyers over a period of 18 months. Huawei also said Wednesday that the US congressional committee probe which branded the company as a threat to US national security is unlikely to affect its business elsewhere overseas, although the report has prompted Canada and the UK to look into potential security risks, Reuters reported. When asked whether other overseas business would be affected, Huawei Senior Vice President Zhang Chunxiang denied that there would be an impact.
