New York (CNN Business) The Department of Commerce has again extended the temporary general license allowing American companies to sell to Huawei, the embattled Chinese tech company. The existing temporary license was set to expire Monday.

"The Department will continue to rigorously monitor sensitive technology exports to ensure that our innovations are not harnessed by those who would threaten our national security," Commerce Secretary Wilbur Ross said in a statement Monday.

The Trump administration says Huawei's networking equipment carries risks to US national security because its telecommunications gear could be used for spying by Beijing. The US government has also accused Huawei of skirting sanctions and stealing intellectual property from American companies, all claims that Huawei staunchly denies.

In May, the Commerce Department put Huawei on the "Entity List," a trade blacklist that makes it illegal for American companies to do business with it without a license. But the move posed a serious threat to its American suppliers — Huawei is the largest telecom company in the world, the second largest smartphone maker and it buys tens of billions of dollars in products from US companies every year. The action has also weighed on Huawei's smartphone sales.
