A US House of Representatives committee has begun an investigation into the security threat posed by Chinese telecommunications firms that operate in the US, such as Huawei and ZTE. The House Intelligence Committee is concerned that China could use telecommunications equipment for espionage or sabotage. "The fact that our critical infrastructure could be used against us is of serious concern," AFP reports citing committee chairman Mike Rogers. "The purpose of this investigation is to determine to what extent Chinese communications companies are exploiting the global supply chain and how we can mitigate this threat to our national and economic security," Rogers said.
