The Wang Lijun incident was a major Chinese political scandal which began in February 2012 when Wang Lijun, vice-mayor of Chongqing, was abruptly demoted, after revealing to the United States consulate details of British businessman Neil Heywood's murder and subsequent cover-up. Amidst rumors of political infighting with Chongqing Communist Party secretary Bo Xilai, Wang arranged a meeting on 6 February at the US consulate in Chengdu, where he remained for over 30 hours. Observers speculated that Wang may have been attempting to defect or to seek refuge from Bo. He then left the consulate of his own volition and was taken to Beijing by agents and the vice minister Qiu Jin (邱进) of the Ministry of State Security. The Chongqing municipal government declared that Wang was receiving "vacation-style medical treatment".

Bo Xilai is a Chinese former politician who was convicted on bribery and embezzlement charges. He came to prominence through his tenures as Mayor of Dalian and then the governor of Liaoning. From 2004 to November 2007, he served as Minister of Commerce. Between 2007 and 2012, he served as a member of the Politburo of the Chinese Communist Party (CCP) and Communist Party Secretary of Chongqing, a major interior municipality. He was generally considered the main political rival of Xi Jinping before Xi became the paramount leader of China.
