Qualcomm has received permission from the US to sell 4G mobile chips to Huawei, an exemption to the Trump administration’s ban on doing business with the Chinese company. Qualcomm did n’t specify which products it’s allowed to sell to Huawei.

In May 2019, the White House issued an executive order barring US companies from doing business with Chinese companies like Huawei. In May of this year, the US began requiring foreign semiconductor manufacturers to get a license from the us if they used us equipment or technology to make chips for Huawei.

Huawei said in August it was running out of processor chips because of the US sanctions. Ceo of Huawei’s consumer business unit said at the time that’this year may be the last generation of Huawei Kirin high-end chips’.

Huawei’s shipments dropped 24 percent year over year in October. Samsung saw a 47 percent increase in shipments. Huawei lost the top spot to Samsung last month.
