Following the crash of the Chinese stock market the government is taking precautions to prevent something like it happening in the near future. How they'll do it? They'll launch a stock market circuit-breaker. Would it be a safeguard in case there's a global crash? I doubt it. You can read more about it here: http://www.bloomberg.com/news/artic...rcuit-breaker-to-calm-volatile-a-share-market “The introduction of this mechanism is another effort from China to stabilize the local stock markets, moving it gradually towards that of developed markets,” said Bernard Aw, a strategist at IG Asia Pte in Singapore. “They need more than just circuit breakers to stabilize volumes. Increased institutional and foreign participation is another part of the equation to reduce excessive volatility.”
Additional, related, news on the regulation of the market appears to involve more to the central bank (http://english.caixin.com/2015-11-17/100875163.html) and implementing more control over IPOs (http://english.caixin.com/2015-12-02/100881110.html). I would think China officials want tighter controls in place before next October when the RMB gets added to the basket of currencies (http://www.bullmarketboard.com/thre...MB-to-be-included-in-SDR-basket-of-currencies).
