On July 25th, the Treasury Department announced that President Obama has signed an Executive Order imposing sanctions against significant transnational criminal organizations ("TCOs"). As a result of the Order, any property in the United States or in the possession or control of U.S. persons in which the significant TCOs have an interest is blocked, and U.S. persons are prohibited from engaging in transactions with them. The Order also authorizes the Treasury Department, in consultation with the Departments of Justice and State, to identify for sanctions any individual or entity determined to have materially assisted, sponsored or provided financial, material or technological support for any person whose property and interests in property are blocked pursuant to this Order. The Order immediately designates the following groups: the Brothers' Circle, the Camorra, the Yakuza, and Los Zetas. Treasury Department Press Release.
