Federal prosecutors from New York, California and Arizona joined other federal officials in Washington, D.C., on Tuesday to announce the first public criminal charges from a new task force aimed at preventing countries hostile to U.S. interests from obtaining sensitive technology.

The Disruptive Technology Strike Force is co-led by the U.S. Departments of Justice and Commerce, and Assistant Attorney General Matthew Olsen of the DOJ National Security Division said the group will help different U.S. attorneys’ offices share best practices and work together, even when they’re investigating defendants from different countries.
