Timeline: U.S., HK regulators struggle to get China audit papers

BEIJING (Reuters) - Several current and former KPMG partners are facing contempt proceedings in a Hong Kong court, as liquidators for failed U.S.-listed China Medical step up their action against the auditor over its refusal to produce Chinese working papers.
