The value of domestic and outbound deals in the Chinese merger and acquisition market reached record highs in the first half of 2013, Zero2IPO Group Chairman Ni Zhengdong said on Thursday.

There were 359 domestic deals totaling 40.3 billion yuan ($6.6 billion), with outbound deals valued at 27.6 billion yuan, Ni said.

"Although the growth of the Chinese economy slowed and the IPO window was closed," the M&A sector in China was very active, said Ni.
