Gate-crashing (espionage)

Gate-crashing is a term used to describe the apparent Chinese government practice of pressing Chinese citizens present in the United States into service to make generally unsophisticated attempts to trespass on sensitive U.S. government facilities and areas. The U.S. government views the phenomena as a form of espionage by China intended to test security practices at sensitive installations. The trespassers are typically described as having claimed to be lost tourists.

The term is applied to several related practices: gate-crashers, who physically attempt to force their way past guards and barricades at the entrances of restricted areas like military bases; individuals who are found to have "accidentally" wandered into restricted areas like bases or test ranges from adjacent public areas; and sometimes to describe individuals who fly drones into restricted areas or surveil them with long-range cameras.
