1. US government is preventing Chinese acquisition of both US and foreign companies. [1] 2. Boeing's assembly line in China is Boeing's only oversea factory. All planes assembled in China are for the Chinese market. [2] 3. US laws forbid the State Department issuing me US visas with valid period longer than 12 months because I did high performance computing during PhD (studying parallel computing is not a crime!). Last time when I worked for a major US company, I had to spend months to get clearance to have access to some stupid patent data which is 200% intended for immediate public use. 4. US bans a long list of parts/components to be sold to Chinese/Chinese companies. For example, some public Chinese universities (e.g. BUAA) which have project fundings from the Chinese government are not even allowed to buy DELL desktop computers! US bans AMD from selling its high end GPU to the Chinese government, even when AMD's high end GPU is help designed in Shanghai by a large team of Chinese engineers [3][4].
