Overseas investments high, but success isn't guaranteed

The outlook for investments in China may be uncertain, but Chinese companies' appetite for mergers and acquisitions in developed markets remains at a decade high of 53 deals this year, according to the latest edition of KPMG's High Growth Markets Tracker.

The analysis includes data from completed transactions where a buyer has taken a minimum 5 percent stake in an overseas company.

At the same time, developed markets' acquisitions in China in the first half of 2015 dropped 27 percent from six months ago to a 10-year low of 70 deals.
