Abstract: With the intensification of Sino-US trade frictions, the United States has implemented more stringent and discriminatory export control for high-tech products for a long time, including long-arm jurisdiction and foreign investment review system. Based on the literature review, we analyze the development of the U.S. export control system, the long-arm jurisdiction and foreign investment review system. Then we propose suggestions for Chinese government to optimize the domestic export control system. We also provide advices for Chinese companies to respond to the long-arm jurisdiction and reduce overseas business risks effectively.
