The US should nip all exports to Huawei and SMIC in the bud. That’s what a US lawmaker is demanding. It was recently reported that Huawei is supplying a Chinese SMIC SoC for the Mate 60 Pro, possibly in violation of US-imposed trade restrictions.

According to Republican Mike Gallagher, the Mate 60 Pro’s advanced Kirin 9000s SoC “could not have been manufactured without using US technology” and therefore would have violated US export restrictions. Reuters writes. Michael McCaul, the Republican chairman of the House Foreign Affairs Committee says according to Bloomberg SMIC ‘appears’ to have breached US sanctions.

Gallagher is therefore calling for a complete ban on all US technology exports to both Huawei and SMIC. This is “to make clear that any company that undermines our law and national security will be isolated from our technology.”

Hawaii was banned by the US in December 2019 Company list placed Since then, suppliers must obtain government approval to do business with a Chinese technology company. Some companies, such as Qualcomm and Intel, are still allowed to supply Huawei with technology unrelated to 5G under certain conditions. Stricter export controls were introduced last year, even for exports of advanced chips and chip manufacturing equipment. Companies wishing to export such chips or machines to Chinese companies must now apply for a permit. SMIC was, inter alia, blacklisted, effectively barring the export of such machines to the company.

TechInsides discovered this week that the Huawei Mate 60 Pro may have used US technology without permission. The phone’s Kirin 9000s SoC is based on SMIC’s N+2 7nm process. Although it is not known which production machines SMIC uses, these may include high-end immersion lithography machines from ASML.
