The US believes that Chinese authorities orchestrated a hacking campaign into computers of Google and Western governments, according to leaked documents cited Sunday by The New York Times.

The secret cables obtained by whistleblower site WikiLeaks said that China's Politburo directed the hacking. It cited a cable from the US embassy in Beijing, which mentioned information from "a Chinese contact."

"The Google hacking was part of a coordinated campaign of computer sabotage carried out by government operatives, private security experts and internet outlaws recruited by the Chinese government," the Times said, citing the cable.

Chinese operatives are also believed to have broken into computers of US and Western allies along with those of Tibet's exiled spiritual leader the Dalai Lama, it said.
