Chinese shares fell on สูตร slot xo but trimmed earlier losses amid volatile trade as state-run financial media called for calm following a wild rout triggered by investor concerns about tightening government regulation.

The Shanghai Composite Index fell as much as 2 per cent before finishing the morning session down 0.59 per cent. The blue-chip CSI300 index clawed back some its losses to end the morning flat, but was still down more than 6.6 per cent for the week.

In Hong Kong, the benchmark Hang Seng Index flitted between gains and losses to fall 0.24 per cent at midday after plunging an eight-month closing low a day earlier. The Hang Seng China Enterprises Index was up 0.38 per cent.

Andy Maynard, head of equities at China Renaissance in Hong Kong, said the market mood on Wednesday was "nervous" rather than panicked.

"Is the downside over? No it's not. Do we think there's going to be more? Yes, there probably is. Do I think there's some relief here? Yes."

The Hang Seng Tech index, which hit record lows a day earlier, was barely lower. Real estate firms in Hong Kong rose 1.5 per cent even as a mainland index tracking the sector fell 0.45 per cent.

A CSI index tracking education firms listed on mainland and Hong Kong markets fell 0.52 per cent.
