The fall in the Chinese stock exchange followed a switch in sentiment, with investors appearing to finally heed warnings from regulators that stock prices were vastly overvalued.
Comments from Alan Greenspan, the former Federal Reserve chairman, and rising tension about Iran's nuclear programme also served to undermine investor confidence.

An investment manager at Meeschaert, Alice Lhabouz, said analysts had interpreted Greenspan's comments as a concerted effort by the Federal Reserve to calm financial markets after recent sharp increases.
Francois Xavier-Chevallier, an analyst at French brokerage Credit Mutuel CIC, said that Greenspan "thinks that it is better to have a little crisis now rather than a big crisis at a later date".
