On May 15, 2019, President Donald Trump signed an executive order (EO) declaring a “national emergency” related to certain threats against information and communications technology and services (ICTS) in the United States and authorizing the Department of Commerce to block transactions that involve ICTS with a “foreign adversary.” The EO provides for the possibility of a licensing regime that could allow transactions that would otherwise be blocked. The EO is available here.
The EO itself does not mention any particular countries or companies that would be subject to its prohibitions. However, the EO is widely reported to be aimed at China. Indeed, tensions between the United States and China have intensified over the past week, after negotiations between the two governments to resolve their trade dispute stalled.
