"Using our broad investigative and enforcement authorities and global reach, HSI will continue to work alongside our federal partners to protect U.S. national security interests and inflict maximum disruptive effects against anyone who violates these sanctions in an effort to support the Russian government." The Boeing last flew into the United States in March 2019 when the plane flew from overseas to Houston with LUKOIL officials, including a Russian oligarch – then LUKOIL president and CEO Vagit Alekperov – on board the aircraft. The Boeing is believed to be in Russia and worth approximately $45 million. Since September 2014, LUKOIL has been subject to sectoral sanctions imposed by the Department of the Treasury's Office of Foreign Assets Control.
