(Yicai Global) Sept. 9 -- China's mainland stock markets walked back some of their morning plunges that were two major benchmarks' biggest in over a month while growth shares in Shenzhen were faring the worst amid global sell-offs.

The ChiNext Price Index, which tracks growth enterprises listed in Shenzhen, dipped more than 5 percent to touch its lowest in more than two months. The index was 3.46 percent down at 2,558.93 by the lunch break.

The Shanghai Composite Index moved 1.07 percent lower to 3,280.96 by noon. Before that, it had been more than 2 percent down at its weakest in six weeks. The eastern city's Star Market 50 Index was down 2.39 percent at 1,312.43 after sliding as much as 4 percent earlier.

The Shenzhen Component Index stood at 12,999.02, down 2.21 percent, after slumping 3.8 percent.
