According to Wall Street Journal sources, the proposal is meant to limit the amount of equipment and services purchased from Chinese companies Huawei and ZTE. Huawei in particular has been a focus of the US government. Earlier this year, Congress proposed a bill that would prohibit any government agency from engaging with Huawei and ZTE. And while in January, AT&T did an about face and decided it wouldn't sell Huawei smartphones, reports later surfaced that Congress had pressured AT&T into dropping its rumored plans to carry Huawei products. Since then, Verizon also decided to cancel plans to sell Huawei-manufactured devices while Best Buy announced it would stop ordering them and phase them out.

In February, CNBC reported that six top intelligence chiefs, including those that head the FBI, CIA and NSA, warned US citizens against purchasing Huawei products with FBI Director Christopher Wray telling the Senate Intelligence Committee, "We're deeply concerned about the risks of allowing any company or entity that is beholden to foreign governments ... to gain positions of power inside our telecommunications networks."

The pushback from the US government stems from a belief that Huawei and other China-based firms might be influenced by or could work alongside the Chinese government, exposing the US to state-sponsored cyberattacks or data breaches. Huawei, however, has maintained that it's independent of the country's government and doesn't pose a cybersecurity risk to the US or any other country.

"Threats to national security posed by certain communications equipment providers are a matter of bipartisan concern. Hidden 'back doors' to our networks in routers, switches -- and virtually any other type of telecommunications equipment -- can provide an avenue for hostile governments to inject viruses, launch denial-of-service attacks, steal data, and more," Pai said in his statement today, which didn't go so far as to name either Huawei or ZTE. "Although the FCC alone can't safeguard the integrity of our communications supply chain, we must and will play our part in a government- and industry-wide effort to protect the security of our networks."

If accepted, the proposed rule would largely affect small, rural-based wireless and broadband providers in the US. The proposal will go up for a vote during the FCC's April 17th meeting.
