I'm not surprised by the Chinese reaction. The US government is currently almost at war with Huawei who not only make phones, but in a far larger scale a lot of the technology used by Mobile Operators at base stations and in their data centres. The US has had their CFO arrested in Canada, and is trying to extradite her to the US, and leaning hard on their allies to restrict use of their technology.
The opportunity to put restrictions in a semi-legitimate and public way against a major US company I am sure did not pass the Chinese government by.
