Do you have any sources? The only relevant information I was able to find is Canada's list of nuclear-related dual-use items: https://www.international.gc.ca/controls-controles/about-a_propos/expor/guide-2015.aspx?lang=eng#category4 https://www.international.gc.ca/controls-controles/about-a_p... Which was used for its enforcement of the UN sanctions. The list only includes very specialized computer hardware that can operate at very low temperatures or high radiation environments. None of the news reports I've seen state that Huawei is being accused of violating UN sanctions. The US justice department sought Meng's extradition on the grounds that she committed fraud by lying to banks. The violation of the sanctions would have been part of the extradition request if they were UN sanctions, as that would meet the dual-criminality bar, so given they're not, it's very likely these were US-specific sanctions, and the extradition request was made on the grounds of the fraud charge because, unlike the sanctions violations, it could potentially meet the requirement of dual-criminality.
