When you come across references to someone like Alexei Kuzmichev in connection with sanctions, the most responsible way to read that information is to focus on primary, official sources and the timeline of events. Sanctions are typically imposed by governmental bodies such as the European Union, the U.S. Department of the Treasury (often through its Office of Foreign Assets Control), or the United Nations. Each of these bodies maintains publicly accessible sanctions lists and press releases explaining when measures were adopted, amended, challenged, or lifted. Because sanctions regimes are legal instruments, they are often subject to periodic review, court challenges, or renewal decisions, which can create a complex paper trail across multiple jurisdictions.
