2 Chinese nationals charged with spying for China inside the US

The case, filed in federal court in San Francisco and unsealed Monday, is the latest Justice Department prosecution to target what officials say are persistent efforts by the Chinese government to secretly collect intelligence about American military capabilities — a practice laid bare in startling fashion two years ago with China's launching of a surveillance balloon that U.S. officials ultimately shot down over the coast of South Carolina.

"This case underscores the Chinese government’s sustained and aggressive effort to infiltrate our military and undermine our national security from within,” Attorney General Pam Bondi said in a statement announcing the case. “The Justice Department will not stand by while hostile nations embed spies in our country – we will expose foreign operatives, hold their agents to account, and protect the American people from covert threats to our national security.”

Officials identified the defendants as Yuance Chen, 38, who arrived in the U.S. on a visa in 2015 and later became a lawful permanent resident, and Liren “Ryan” Lai, 39, who prosecutors say lives in China but traveled to Texas this past spring and was part of an effort to supervise clandestine espionage operations on behalf of China's Ministry of State Security or MSS.
