•U.S. officials are using temporary devices to avoid surveillance during Trump's China visit.
•China is designated as a high-risk country for cyber threats, prompting extreme security protocols.
•Officials are prohibited from using local Wi-Fi and charging stations to prevent hacking.

During President Donald Trump's visit to China, U.S. officials are operating under a strict 'digital lockdown' due to concerns over cyber espionage. Delegation members, including executives from major corporations, left personal devices behind and were issued temporary 'clean' phones and laptops to minimize surveillance risks. The U.S. government has classified China as a high-risk environment for cyber threats, prompting these extreme security measures. Officials have been advised against using local Wi-Fi and charging stations, with specific warnings about 'juice jacking'—a method of malware installation via public charging ports. Communication is restricted to controlled channels, and sensitive discussions are held in specially designed Sensitive Compartmented Information Facilities (SCIFs). The measures reflect ongoing tensions between the U.S. and China regarding cyber espionage and security. The situation complicates diplomatic and business communications during the visit.
