Bao Tong (Chinese: 鲍彤; 5 November 1932 – 9 November 2022) was a Chinese writer and activist. He was Director of the Office of Political Reform of the Central Committee of the Chinese Communist Party (CCP) and the Policy Secretary of Zhao Ziyang (Chinese Premier from 1980 to 1987 and CCP General Secretary from 1987 to 1989). He was also Director of the Drafting Committee for the CCP 13th Party Congresses, known for its strong support of market reform and opening up under Deng Xiaoping. Prior to this, he was a committee member and then deputy director of the Chinese State Commission for Economic Reform. During the 1989 Tian’anmen square protests, he was one of the very few Chinese senior officials to express understandings with the demonstrating students,June Fourth incident.

Bao was born in Haining, Zhejiang Province, but he grew up and received his primary and secondary education in Shanghai.Wu Shichang (a well-known political commentator in the 1930s-1940s and major contributor to The Observer, a key journal of Chinese liberal intellectuals), Bao turned to political liberalism and left-wing ideology promoted by the CCP, when he was still a high school student.Shanghai Nanyang High School where he met his wife, Jiang Zongcao.Chinese Communist Party in 1949, the year it came to power following the civil war.Beijing with his wife Jiang Zongcao, his daughter Bao Jian, and granddaughter Bao Yangyang.

He was Director of the Drafting Committee for the CCP 13th Party Congresses, prior to which he was a committee member and then deputy director of the Chinese State Commission for Economic Reform. Bao was the political secretary of the Politburo Standing Committee between November 1987 and May 1989.: 41

On 28 May 1989, he was arrested in Beijing just before the suppression of the democracy movement in Tiananmen Square on June 4, 1989. Zhao Ziyang had resigned as General Secretary of the Chinese Communist Party in protest when Deng Xiaoping made the decision to crack down on the students. Bao Tong was a close associate of Zhao and the writer of his speeches and editorials supporting a democratic and legal approach to the student movement. Zhao was held under house arrest for the rest of his life, while Bao Tong was officially charged with "revealing state secrets and counter-revolutionary propagandizing", the highest government official to be charged in relation to the 1989 movement. He was publicly convicted in 1992 in a brief show trial and sentenced to seven years" imprisonment with two years deprivation of political rights. He served his full sentence in isolation at Qincheng Prison.

On 27 May 1996, when he was due to be released upon completing his prison sentence, he was instead held at a government compound in Xishan (outside Beijing) for an additional year, until his family agreed to move out of their apartment in town to one allocated for them by the authorities, where a 24-hour guarded gate and surveillance cameras were installed. Visitors were screened, the phone was tapped or cut off entirely, and Bao Tong was followed by an entourage of men the moment he stepped out of his home. Though he had moved to another apartment in Beijing, the system of surveillance and curtailing his phone calls, visitors and movements had followed him to his new home.

Bao Tong appealed for the restoration of civil and political rights of Zhao Ziyang from 1998 until Zhao"s death. He was instrumental in the publication in May 2009 of Zhao Ziyang"s memoir, based on audiotapes that Zhao made secretly while under house arrest and discovered after his death in 2005. Bao Tong"s son Bao Pu, and daughter-in-law Renee Chiang, published the book Journey of Reform (改革歷程) in Hong Kong and translated and edited (along with Adi Ignatius) an English version of this book entitled Prisoner of the State: The Secret Journal of Premier Zhao Ziyang. Bao Tong wrote an introduction for the Chinese version.

Bao Tong continued to write articles openly critical of the government and its policies. He supported further democratic development in Hong Kong and continued to voice the need for political reform in China.Charter 08 manifesto and called for the release of Liu Xiaobo, an organiser of the charter who was arrested in December 2008.

On 19 January 2005, the Washington Post reported that Bao Tong and his wife were injured in attacks by more than 20 plainclothes security agents as they attempted to leave their home to pay their respect to the family of Zhao Ziyang, who died on 17 January. The authorities would only allow him access to a doctor if he removed a white flower (traditional symbol of mourning) pinned to his vest. He refused.

On 1 January 2007, Reuters tested a new government relaxing of regulations on foreign reporters by visiting Bao Tong at his home, purportedly to conduct an interview about the 2008 Summer Olympic Games. Since then, several foreign reporters have done the same. The guards sometimes attempt to intimidate or deny visitation, but were apparently allowing most foreign reporters to enter, if prior arrangements were made. Local Chinese reporters were not included in this new relaxation of regulations.

Their home telephone continued to be tapped and periodically cut off, especially when overseas callers asked to speak to Bao Tong. He was followed everywhere he went, and was occasionally blocked from "sensitive" events or places, for example, the home of Zhao Ziyang while he was alive, and his funeral after his death in 2005. Bao was allowed to leave Beijing on three occasions since his arrest in 1989, the last time in 2009 for a holiday by invitation and escort of the Public Security from 22 May to 7 June, neatly avoiding the 20th anniversary of the Tiananmen Massacre. Visits from his son, Bao Pu, a resident of Hong Kong, were permitted by special arrangements only; under normal circumstances of application, he was unable to obtain a visa.

Bao died in Beijing on 9 November 2022, at the age of 90; the death was announced on Twitter by Bao Pu.Gao Yu, a close friend of Bao, stated that he had died of myelodysplastic syndrome, and that the funeral would take place on 15 November 2022.

Bao Tong, who was the highest-ranking Chinese official imprisoned over the pro-democracy protests in Tiananmen Square that ended in mass carnage in 1989, and who later became an acerbic outsider-critic of the Communist Party, died on Nov. 9 in Beijing. He was 90.

In the mid-1980s, he was central to devising Mr. Zhao’s political reform proposals to rein in the party’s power and expand public oversight of officials. In his later years, he saw little near-term hope that the party would reopen the way for democratic changes, yet he stayed optimistic that China would eventually take that path. And that shift, Mr. Baosaid, would demand confronting the traumas of June 1989, when troops shot protesters in Beijing and other Chinese cities, with estimates of the death toll ranging from the hundreds to the thousands.

“The ‘June 4’ student democracy movement of 1989 was the great event, the one most worthy of the Chinese people’s pride, that I experienced in my life,” Mr. Bao wrote this year in an article for Radio Free Asia. But the bloodshed, he added, had “brazenly opened up a new era where state power has no constraints and civic rights have lost their safeguards.”

Bao Tong was born on Nov. 5, 1932, in Haining, Zhejiang Province, in eastern China, the third of six children. His father, Bao Peiren, a manager in an enamel products factory, and his mother, Wu Heng, a homemaker, immersed their children in learning.

He was working in the State Science and Technology Commission in 1980 when Zhao Ziyang, a provincial leader with a reputation for innovation, was promoted to the central leadership in Beijing. Mr. Bao became his secretary, advising him on policy decisions and helping him navigate the political currents of the post-Mao, market-friendly era of Deng Xiaoping.

“We worked together, we ate together — in the first year we even didn’t have any weekends,” said Wu Guoguang, a professor at Stanford University who had been recruited to help in Mr. Bao’s office. The work led staff members to suffer teeth problems, insomnia and exhaustion. “Bao Tong disease,” they called it.

Mr. Bao read widely, from classical Chinese texts to Anne Rice’s “The Vampire Chronicles,” his son said. He also jumped over China’s censorship wall to use Twitter, where he described himself as a “Chinese citizen.” After Mikhail Gorbachev’s death this year, he tweeted: “Bao Tong bows in respect.”
