China won't reintroduce stocks circuit breaker soon: securities regulator

China will not reintroduce the circuit breaker mechanism to its stock markets in the next few years, Liu Shiyu, chairman of the China Securities Regulatory Commission (CSRC), told reporters in Beijing on Saturday. A circuit breaker mechanism introduced in January by Liu's predecessor Xiao Gang was dismantled after only a few days. China's Shanghai and Shenzhen stock markets slumped as much as 40 percent in just a few months last summer.
