Huawei has been handed a 45-day reprieve licence by the US Commerce Department.
After the company was blacklisted by the US government from using their products last May, the firm obtained a temporary licence allowing US companies to do business with them and now they have had it extended.
However, their previous 90-day reprieves in May, August and in November is now been cut down to half the time.
The Commerce Department insisted they have extended it again "to prevent interruption of existing network communication systems in rural U.S. regions and permit global network security measures."
They added: "The 45-day extension is necessary to allow existing telecommunication providers - particularly those in rural US communities - the ability to continue to temporarily and securely operate existing networks while they identify alternatives to Huawei for future operation."
Huawei has previously insisted they have been treated "unfairly".
