Since the establishment of the People’s Republic of China in 1949, intelligence services in both Beijing and Washington have vied to uncover secrets in one another’s countries, and to safeguard their own secrets, in pursuit of military, economic, and technological advantage. Many bona fide spies on both sides have been caught; many innocents have been unfairly implicated. What follows is a brief history of key events in this conflict.
Qian Xuesen, cofounder of the Jet Propulsion Laboratory and professor at Caltech, is stripped of his security clearance for alleged connections to the Communist Party. Qian, who had questioned Nazi rocket scientists on behalf of the US government after World War II and worked on the Manhattan Project, resigns from Caltech and asks to leave the US for China, at which point he is held under house arrest for five years. In 1955 the US deports him; Qian is greeted as a hero in China and goes on to become the father of Chinese rocketry, helping jump-start China’s space and missile programs. No substantive evidence has ever been released that he was a Chinese spy. Deporting Qian was “the stupidest thing the country ever did,” according to Dan Kimball, undersecretary of the Navy at the time of Qian’s arrest.

Wen Ho Lee, an American citizen born in Taiwan, pleads guilty to one count of illegally possessing government data related to national security and is released for time served. The government’s case alleging that Lee was a super spy who helped China develop a next-generation nuclear warhead ultimately collapses, and the judge overseeing Lee’s case apologizes for the way Lee was treated (including solitary confinement). Though many of Lee’s actions remain mysterious, few suspect he was ever a Chinese spy. Lee goes on to win a $1.6 million settlement from the government and several news organizations for leaking and publishing his name before he was formally charged. The supposed mole who stole nuclear secrets has never been found.

In March 2008, Chi Mak is found guilty and sentenced to 24 years in prison for conspiring to export military technology to China, among other crimes. The prosecution argued that Chi was a sleeper agent when he came to the US in the 1970s and worked his way up as an engineer at a defense contractor. Many of the alleged secrets were not revealed, but Mak is believed to have passed intelligence related to quieting submarine propulsion to avoid detection.

Chun, who was found to have made millions of dollars selling secrets to China, claimed he was merely a pack rat hoarding classified documents.

The Office of Personnel Management announces a massive security breach that eventually is shown to affect over 20 million people who had undergone background checks for federal jobs since 2000. These records included sensitive information like psychiatric history, as well as over 5 million sets of fingerprints. Chinese military unit 61938 is suspected of conducting the hack. The records are highly valuable to the Chinese as a database of government employees to target as informants, aided by the sensitive information on those employees.
Ex-CIA officer Kevin Mallory is arrested for passing classified materials to Chinese intelligence agents using a cell phone given to him during a trip to Shanghai. Mallory, who volunteered some information to FBI and CIA agents before being arrested, had claimed to be a double agent helping the US government, but after the FBI cracked his phone, he was shown to have hidden information. Behind on his mortgage and in debt, he had received $25,000 from the Chinese. In June 2018 a jury finds him guilty of espionage, and he is later sentenced to 20 years in prison.
Ex-CIA agent Jerry Chun Shing Lee is arrested at JFK Airport and charged with giving Chinese agents classified information from his days at the CIA, including the real names and locations of assets in China.

According to prosecutors, Lee’s information helped dismantle the CIA’s China network in 2010.
Ron Rockwell Hansen, a former Defense Intelligence Agency officer, is arrested at Seattle-Tacoma International Airport carrying classified information about military readiness plans. In March 2019 Hansen pleads guilty and admits to agreeing to pass military secrets to Chinese agents in exchange for hundreds of thousands of dollars.
