Patent filings reveal that Huawei has made advances in a crucial method of chip manufacture, raising the prospect that the company could eventually start making some of the smallest and most powerful microchips by itself.Washington, Brussels and London are currently all blocking access to advanced Western-made computer chips in China over fears the Communist nation could develop new military capabilities beyond the power of Western armies to resist.In an end-of-year message Chairman Eric Xu said the company had emerged from “crisis mode”, saying: “US restrictions are now our new normal, and we're back to business as usual”.Other Western nations followed with similar bans, including an order from then Prime Minister Boris Johnson to remove Huawei equipment from key British telecommunications infrastructure in 2020.Sanctions sent Huawei’s global revenues plummeting by a third in 2021 but Mr Xu said Huawei’s sales for 2022 were on track to be flat at around 636.9bn yuan (£76.6bn)."
