中国及亚洲股市周三震荡

Major stock markets in China and elsewhere in the region saw another day of volatile trading Wednesday, as the head of the IMF warned that concerns over Asia's economy are reverberating across the globe.

Shanghai stocks plunged nearly 4.5 percent at opening, before recovering to positive territory at the break. Just before the close, the benchmark Chinese index was down about 1 percent.

In Tokyo, the Nikkei also tumbled in morning trading, but ended the day down only four-tenths of one percent. Trading was basically flat in Seoul and Sydney.

The early morning Asian sell-off came after a poor day on Wall Street, where main indexes lost about 3 percent on Tuesday, as fears grew about a slowdown in the world economy.
