Liu was a senior investigative reporter for 南方周末 (Southern Weekly), considered to be China's most influential investigative newspaper. He provided front-line and in-depth coverage of the burgeoning Chinese environmental movement. He was the first one to discover and claim that China's emerging environmental movement is a new democratic movement. See Liu's article about environmental movement online here 
Some of Liu's most powerful articles include his September 2004 expose on the controversial Tiger Leaping Gorge dams in southern Yunnan province--TIGER LEAPING GORGE UNDER THREAT. When Prime Minister Wen Jiabao read this article, he suspended the dam project and ordered an investigation by the Chinese government. His December 2004 piece on genetically modified rice ignited a central government crackdown on the illegally produced foodstuffs. His March 2005 article on the controversial Summer Palace Lake Reconstruction Project led the State Environmental Protection Administration to hold China’s first ever state-level public environmental hearing.
He was featured in an expose in the Wall Street Journal in December 2006 on the rise of Chinese investigative journalism--China's Reporters Face a Backlash Over Investigations  The WSJ's article on Liu is online here
