On Friday, China announced sanctions against several business units of Lockheed Martin Corp. and barred three of its executives from entering the country. These measures were enacted in response to Lockheed Martin’s arms deals with Taiwan, which China considers part of its sovereign territory. The sanctions were described as symbolic, given the longstanding suspension of military cooperation between the U.S. and China since the events of the 1989 pro-democracy protests. Among the affected entities are Lockheed Martin Missile System Integration Lab, Lockheed Martin Advanced Technology Laboratories, and Lockheed Martin Ventures, while executives James Donald Taiclet, Frank Andrew St. John, and Jesus Malave were specifically named in the travel ban.
