A top U.S. law enforcement official on Thursday unveiled a new “disruptive technology strike force” tasked with safeguarding American technology from foreign adversaries and other national security threats.Deputy Attorney General Lisa Monaco, the No. 2 U.S. Justice Department official, made the announcement at a speech in London at Chatham House. The initiative, Monaco said, will be a joint effort between her department and the U.S. Commerce Department, with a goal of blocking adversaries from “trying to siphon our best technology.” Monaco also addressed concerns about Chinese-owned video sharing app TikTok. The U.S. government’s Committee on Foreign Investment in the United States (CFIUS), a powerful national security body, in 2020 ordered Chinese company ByteDance to divest TikTok because of fears that user data could be passed on to China’s government. The divestment has not taken place.
