Three American citizens who had been detained for years in China were released, a State Department spokesperson said Wednesday.

They are Mark Swidan, Kai Li and John Leung.

Li, 62, who is from Long Island, New York, was detained in 2016 and sentenced to 10 years in 2018 on espionage charges his family says are baseless. Swidan, a Texas businessman in his 40s, had been detained since 2012 and was sentenced to death with a reprieve in 2019 after being convicted on drug-related charges that a United Nations working group said had no evidential basis.

Li and Swidan were considered “wrongfully detained” by the State Department.
