Huawei's Kirin SoCs are developed through their HiSilicon subsidiary and are highly competitive with flagship SoCs from Qualcomm and Samsung. MediaTek are a major player in the budget and mid-range smartphone segments. China lacks mainland fabrication capacity, but Chinese fabless IC companies have very good working relationships with TSMC. Tsinghua Unigroup's bids to buy Micron failed, but they're building a $30bn 3D NAND fab which is due to go online this year. The Chinese government are very serious about building up modern fab capacity. ARM are British, so there's nothing stopping ZTE from licensing the technology they need to develop a flagship SoC. TSMC will happily fab it for them on a modern process node. Huawei have done it, ZTE are undoubtedly doing feasibility studies as we speak and I wouldn't be at all surprised if Xiaomi and Oppo are thinking about it. In the long term, this sanction could massively backfire by pushing Chinese manufacturers to reduce their dependence on American suppliers.
