(Yicai Global) Feb. 14 -- China's stock markets opened a bit lower as investors' euphoria waned and a reality check set in following three days of strong post-holiday rallies from binge-buying of bargains.

The Shanghai Composite Index dipped 0.20 percent to 2,715.54 points. The Shenzhen Component Index stood at to 8,182.32 points, up 0.14 percent. The ChiNext Price Index, which tracks growth enterprises in Shenzhen, was up 0.01 percent at 1,357.78 points.

Investors are leery after these robust gains and fretting over the on-going high-level trade talks between China and the US that began this morning in Beijing, and which will wrap up tomorrow. 

Officials are trying to thrash out a deal to avert punitive higher tariffs on both countries' exports.
