THE HILL: Feds charge six Chinese citizens with spying on Silicon Valley.

The Obama administration announced charges Tuesday against six Chinese citizens suspected in a long-running espionage plot aimed at stealing U.S. technology on behalf of their government.

The action, revealed in newly unsealed indictments, reflects an aggressive push to tamp down on the foreign theft of U.S. trade secrets and, in particular, sends a strong message to Beijing — a top competitor on technology.

Hao Zhang, 36; Wei Pang, 35; and four others were charged with a range of offenses, including conspiracy to commit economic espionage, conspiracy to commit theft of trade secrets, economic espionage and theft of trade secrets.

According to federal prosecutors, Hao and Wei sit at the center of an industrial theft ring that spans years.

If this is a widespread problem, maybe we should be more careful about H1B visas?
