According to two congressional aides, for both national security reasons, U.S. lawmakers urged AT & T, the country's second-largest wireless carrier, to cut off all commercial ties with Chinese handset maker Huawei and oppose Chinese telecom operator China Mobile from entering the U.S. market, Reuters reported.
Sources told Reuters earlier this month AT & T was forced to cancel its plan to provide customers with Huawei handsets after some lawmakers lobbied federal regulators to oppose the plan.
The U.S. government also blocked a series of Chinese takeovers for national security reasons, including the acquisition of MoneyGram by Ant Financial.
A congressional aide said the parliamentarians also told U.S. businesses that their business with Huawei or China Mobile could hinder their ability to deal with the U.S. government. He asked for anonymity because they were not empowered to comment publicly.
Aides said Congress and AT & T hope AT & T cut off one of its commercial ties with Huawei is that the two in the development of next-generation 5G high-speed network standards of cooperation; the other is AT & T's Cricket subsidiary uses Huawei's mobile phone.
China Mobile did not reply to the comment request.
AT & T did not comment but said the company has not yet identified 5G suppliers. None of the U.S. lawmakers who expressed any concerns about the prospect of AT & T and Huawei could reach an agreement in the past did not comment on or could not reach them.
Huawei also declined to comment but told Reuters earlier this week that the company sells products through more than 45 of the world's 50 largest carriers and pays top priority to protect customer privacy and information security.
Michael Wessel, a member of the U.S.-China Economic Security Review Commission (USCC), said that U.S. lawmakers do not want China Mobile to obtain a license to operate in the United States. China Mobile applied for a license in 2011, a request still pending before the Federal Communications Commission (FCC) for approval.
Huawei and China's telecommunications companies have long struggled to gain a foothold in the U.S. market, in part because of the U.S. government's pressure on potential U.S. partners.
Republican lawmakers Michael Conaway and Liz Cheney moved a motion this week to stop the U.S. government from signing contracts with Huawei or ZTE or using its products。
