Executive Order 13943: WeChat and ICT Supply Chain National Emergency
President Trump signed Executive Order 13943 on August 6, 2020, declaring a national emergency regarding information and communications technology and services supply chain threats, specifically targeting WeChat. The order prohibited transactions with WeChat and required the Secretary of Commerce to identify other ICT services posing national security risks within 45 days. The order's implementation was blocked by federal courts before the effective date, preventing the WeChat transaction ban from taking effect.
