The Critical Moment – Li Peng Diaries is a book issued in 2010 in the United States by West Point Publishing House, a small publisher established by Zheng Cunzhu, a former 1989 pro-democracy activist. The book contains entries from a diary believed to be written by the late former Chinese Premier, Li Peng, covering the events leading up to and shortly after the 1989 Tiananmen Square protests and massacre. Soon after the 21st anniversary of the 1989 Tiananmen Square protests and massacre in early 2010, a diary widely believed to have been penned by Li Peng was leaked onto the Internet.

He nevertheless had some reservations, which he had been prepared to set out in a footnote. The South China Morning Post had verified that substantial sections of the book were identical to the Internet manuscript. The newspaper said that Li's book had probably been ready for publication in early 2004 to coincide with the 15th anniversary of the 1989 protests. The SCMP cites the Yazhou Zhoukan saying that the manuscript was submitted for Politburo approval in autumn 2003; he was told several months later clearance had been denied. In June 2010, the diary was leaked onto the Internet. Contents The book takes the form of a series of selected diary entries penned between 15 April and 24 June 1989, revealing that the inner circle of the Communist Party was sharply divided on how to handle the protests.
