Foreign mergers and acquisitions by Chinese investors set a record last year, while domestic purchases marked a pause, a study released on Wednesday by the accounting firm PwC showed on Wednesday. PricewaterhouseCoopers put total Chinese investment abroad in 2012 at $65.2 billion, an annualised leap of 54 percent, a statement said. The number of investments declined slightly meanwhile to 191 transactions from 206 deals in 2011, but they still represented one-third of all Chinese investments, the statement said. PwC forecast another record this year.
