Market drops over 2%

China's main stock index lost more than 2 percent yesterday, ending at a seven-month closing low as concern about monetary tightening led the index to underperform foreign bourses.

Hong Kong's Hang Seng Index and Tokyo's Nikkei 225 rallied more than 1 percent in response to foreign central banks' plan to inject funds into global credit markets.

But the benchmark Shanghai Composite Index, which opened more than 2 percent higher, ended down 2.30 percent at 4070.116 points.
