CHONGQING -- Police here look to work with their American counterparts on an investigation into potentially forged official documents connected to wealthy businessman Guo Wengui, a vocal critic of the Chinese government now accused of donating money to U.S. political campaigns.
Beijing is ratcheting up pressure for Washington to extradite Guo, who seeks asylum in the U.S. and continues to lob allegations of corruption at figures including Vice President Wang Qishan, President Xi Jinping's right-hand man and, until last year, his anti-corruption czar.
