China's mergers and acquisitions volume rose 20 percent month-on-month to 82 deals in August, the best monthly performance this year, Zero2IPO Research said on Wednesday.

Real estate was the most active sector with 12 deals, accounting for 14.6 percent of the total transactions made.

The combined value of the 73 disclosed deals was $1.53 billion.

The average value per deal was $20.97 million, a 40.1 percent month-on-month decrease due to the relatively smaller scale of cross-border M&As.
