President Trump on Wednesday declared a national emergency, signing an executive order that bans U.S. companies from using foreign telecom services that could pose a national security threat.
The move effectively bans companies from using Huawei, China’s largest telecom company.
Trump’s order instructs Commerce Sectary Wilbur Ross to prohibit transactions that pose an unacceptable risk to national security and the safety of U.S. citizens.
The executive order did not name any nation or company, but it has long been expected as U.S. officials have expressed concerns about China using such companies as a means for espionage.
