The Chinese telecom majors ZTE and Huwaei are facing rough weather in the US. The US House intelligence committee is looking into the fact whether these companies are jeopardizing the country’s security by expanding operations.

The probe will investigate whether the companies' presence in the US provides "the Chinese government an opportunity for greater foreign espionage," according to a news release issued by Representatives Mike Rogers, chairman of the House Permanent Select Committee on Intelligence, and Dutch Ruppersberger, the panel's top Democrat.

"The fact that our critical infrastructure could be used against us is of serious concern," Rogers said in the release. Huawei's efforts to expand in the US have been repeatedly blocked by lawmakers concerned about its alleged links to China's military; in February, the US Committee on Foreign Investment forced the company to unwind its acquisition of California-based 3Leaf System's patents, citing a "serious risk" to US computer networks.
