This Chinese-born Swede, right, ran publishing house Mighty Current in Hong Kong, known for printing political gossip about the Chinese leadership. He disappeared from his apartment in Thailand on October 17. Three months later, he suddenly appeared on Chinese state television, confessing to a 2003 hit and run. His supporters say he was kidnapped by Chinese agents and the Thai police tell CNN they have no record of him leaving the country.
Lee Bo —
Gui Minhai's business partner, Lee Bo was last seen on December 30 near his company's warehouse in Hong Kong. Hong Kong police have since confirmed he is in mainland China. Lee's disappearance sparked demonstrations in Hong Kong, where protestors believe his arrest was a violation of the former colony's autonomy. Lee and Gui's supporters say Mighty Current was working on a book about the love affairs of Chinese President Xi Jinping. UK authorities say they are "deeply concerned" about the possible detention of Lee, a British passport holder, and his colleagues.

After speaking to his wife from a train near the Thai-Laos border on January 11, he disappeared for more than three weeks. His wife told CNN the two next spoke on the phone on February 3. Li refused to disclose his location and told her he "voluntarily came back to China to accept an investigation."
Dong Guangping —
A former Chinese police officer, Dong was arrested several times for participating in pro-democracy protests. He fled to Thailand with his family in 2015 seeking safety from Chinese authorities and a better life for his daughter, according to his wife Gu Shuhua. Despite UN recognition as a refugee, the Thai authorities arrested him in October for an immigration violation. Gu says her husband's immigration fine was paid by the Chinese government who then took him back to China. Since his arrest in Bangkok, she says her only contact with Dong has been seeing him in police custody on Chinese state television.

He appeared imprisoned on Chinese state television in November, asking for "lenient treatment."
Bao Zhuoxuan —
A 16-year-old student, Bao fled China after the detention of his parents in a government crackdown on human rights lawyers.

Chinese state media denied reports the boy has been threatened or harassed and said he is enrolled in local school.
