The US had banned the sales and licensing of Matlab to the seven military-related Chinese universities or institutes over a year ago, apparently causing some inconvenience to these institutes, because Matlab is used in many industries. They had to scramble to find alternatives. Some of these universities, for example NPU (Northwestern Polytechnical University), are well-known in conducting (very successful) hypersonic R&D.
So the US apparently had "aided" the development of Chinese military R&D, including hypersonics. I'm even sure these universities are still using PCs equipped with Intel CPUs. By that logic, Intel is also guilty of assisting Chinese military-industrial-complex.
Where do we draw the line?
