China's stock market has had a spot of trouble lately. Perhaps you've heard? You may also know that the Chinese government has intervened heavily to try to prevent a financial panic. And yet, as the Wall Street Journal notes today, the stock market remains well off its peak.
Whether Beijing's policy has "worked" is somewhat subjective; if you think that financial panic was imminent, then maybe it has. But even if you think that the government's policies have prevented a disaster, you still have to ask whether they can actually sustain a recovery.
