China has reportedly blocked all Google services days before the 25th anniversary of the military clampdown on the student protest centered around Beijing's Tiananmen Square.

Cnet.com, citing a Chinese news website, reported Monday that Chinese users have found Google's services to be inaccessible since last week.

The reported blockage, which has not been confirmed by the Chinese government, is believed to be a deliberate act of censorship leading up to June 4 -- the 25th anniversary of the 1989 Tiananmen Square Massacre in which mass numbers of unarmed Chinese protesters were killed, injured or arrested.

Other online sites, including certain social networks, are also inaccessible to Chinese users, according to reports.

A Google spokeswoman was not immediately available when contacted by FoxNews.com.

China has a history of censorship ahead of the Tiananmen anniversary. The ruling party prohibits public discussion, and all events from 1989 are banned from textbooks and Chinese websites.

A Chinese-born Australian artist and former protester in China's 1989 pro-democracy movement was recently taken away by Chinese authorities shortly after a profile of him appeared in the Financial Times newspaper in commemoration of the 25th anniversary of the military crackdown.

An Associated Press reporter talked to Guo Jian as he was taken away from his home in suburban Beijing on Sunday night. Guo said he would be held by police until June 15.

Guo's ordeal is the latest in a string of detentions of artists, lawyers, scholars and journalists ahead of the Tiananmen anniversary amid intense government efforts to deter coverage by foreign media of its remembrance.
