Zhang Kunsheng

In 2015, Zhang was placed under investigation by the Communist Party's anti-corruption agency for "suspected disciplinary violation." The year after, despite lack of concrete evidence, he was expelled from the Communist Party. The accusations levied against Zhang have been questioned by analysts, who suspect the arrest was politically motivated. As the most the most senior diplomat in the Ministry of Foreign Affairs to have been arrested during the anti-corruption campaign, Zhang has yet to be formally accused of any crime by any judicial body.

Zhang also served as Counsellor of the Department of North American and Oceanian Affairs of the Ministry of Foreign Affairs of the People's Republic of China from 2001 to 2003, Counsellor of the General Office of the Ministry of Foreign Affairs from 2003 to 2007, and Director-General of the Protocol Department of the Ministry of Foreign Affairs from 2007 to 2011. He was promoted to Assistant Minister of Foreign Affairs in 2011.

Zhang was born and raised in Kunming, Yunnan, while his ancestral home in Shanxi. He graduated from Peking University in 1995, with a Doctorate in International Politics. He was assigned to Ministry of Foreign Affairs (MFA) in 1985. In 1997 he became the First Secretary of Embassy of China in Washington, D.C., a position he held until 2001. During this time, Zhang helped plan the official state visit of Jiang Zemin to the United States of America.
