Shanghai shares opened 2.23 percent higher on Friday, after authorities suspended a "circuit breaker" mechanism that this week twice automatically closed the markets early, fuelling a global market rout.

The benchmark Shanghai Composite Index rose 69.63 points to 3,194.63, while the Shenzhen Composite Index, which tracks stocks on China's second exchange, added 2.25 percent, or 44.12 points to 2,002.21.
