The deal also requires him to submit to polygraph tests, whenever requested by the US government, for the rest of his life.
"I hope God and America will forgive me for what I have done," Ma, who has been in custody since his 2020 arrest, wrote in a letter to Chief US District Judge Derrick Watson in Honolulu ahead of his sentencing.
He would have been allowed to withdraw from the agreement if Watson rejected the 10-year sentence.
Ma was born in Hong Kong, moved to Honolulu in 1968 and became a US citizen in 1975.He joined the CIA in 1982, was assigned overseas the following year and resigned in 1989. He held a top secret security clearance, according to court documents.
Ma lived and worked in Shanghai before returning to Hawaii in 2001. At the behest of Chinese intelligence officers he agreed to arrange an introduction between officers of the Shanghai State Security Bureau and his older brother - who had also served as a CIA case officer.During a three-day meeting in a Hong Kong hotel room that year, Ma's brother - identified in the plea agreement as "Co-conspirator #1" - provided the intelligence officers a "large volume of classified and sensitive information," according to the document.
They were paid US$50,000 (HK$390,000) and prosecutors said they had an hour-long video from the meeting that showed Ma counting the money.Two years later, Ma applied for a job as a contract linguist in the FBI's Honolulu field office. By then, the Americans knew he was collaborating with Chinese intelligence officers and they hired him in 2004 so they could keep an eye on his espionage activities.
The brother was never prosecuted. He suffered from debilitating symptoms of Alzheimer's disease and has since died.Associated Press
