U.S. President Donald Trump faced a challenging two-day summit in Beijing, China, without access to his personal cellphone, a logistical hurdle imposed to safeguard sensitive information from potential hackers. This restriction is standard for all travelers to China, with the State Department advising that there is no expectation of privacy on mobile networks in the country. As a result, Trump and his White House staff resorted to using burner phones and email addresses, which are designed to minimize data exposure. These devices were stripped of most functionalities to ensure security. Personal devices were kept on Air Force One in Faraday bags, which block all signals, thus protecting sensitive data from remote hacking. Despite the digital restrictions, Trump engaged in critical discussions with Xi Jinping, addressing issues such as the Iran war, Taiwan, and trade relations. The summit also included a ceremonial welcome and a state banquet, where a Chinese band performed Trump's favorite campaign song, 'YMCA.' The president will regain access to his personal devices upon boarding Air Force One, which is treated as American territory and equipped to protect sensitive information.
