Chinese shares closed slightly higher on Thursday, lifted by strong performances by non-ferrous metals and cement shares, although investors still traded cautiously amid generally positive market sentiment. The benchmark Shanghai Composite Index rose 0.28 percent, or 6.11 points, to end at 2,168.35 points. The Shenzhen Component Index finished at 8,693.23 points, up 0.62 percent, or 53.66 points. Combined turnover on the two bourses edged up to 150.5 billion yuan (23.93 billion U.S. dollars) from 141.2 billion yuan the previous trading day.
