3 Americans, Including F.B.I. Informant, Are Said to Be Freed in China Swap

The Biden administration has negotiated a prisoner swap with China for the release of three American men, including one who had been an F.B.I. informant, according to senior U.S. officials.

The three Americans — John Leung, Kai Li and Mark Swidan — were on planes heading to the United States on Wednesday morning.

Mr. Leung was outwardly pro-Beijing. He backed the country’s claim to Taiwan, organized groups that promoted American ties with China and frequently appeared with Chinese consular officials in Houston. He had also provided information to the F.B.I. for years, according to two of the American officials, who spoke on condition of anonymity because they were not authorized to discuss details of the matter.

His F.B.I. contacts discouraged him from traveling to China in 2021, one of the officials said. The Chinese authorities arrested him and took him to an undisclosed detention center. For over two years, his friends and family heard nothing. In 2023, a court in the city of Suzhou sentenced him to life in prison, a first for an American charged with espionage in China.

The swap has been in the works for months. It involves the release of at least one Chinese prisoner in the United States, two of the officials said. A State Department official in Washington confirmed the names of the Americans being released but would not give further details.

During the negotiations, multiple American officials said they were in discussions about releasing Xu Yanjun, a Chinese intelligence officer serving prison time in the United States. The terms of the swap were unclear on
