China securities regulator: won't re-introduce circuit breaker in next few years

China won't reintroduce the circuit breaker mechanism in its stock markets in the next few years, Liu Shiyu, chairman of the China Securities Regulatory Commission, 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.
