Chinese shares plunged 6.3 percent Monday after the country's securities regulator imposed margin trading curbs on several major brokerages, a possible sign that authorities are trying to rein in the market's big gains. Other Asian stock markets were mostly higher.

KEEPING SCORE: The Shanghai Composite Index was down 6.3 percent at 3,163.72. Its dive rubbed off on Hong Kong where the Hang Seng was off 1.1 percent at 23,840.91. Japan's Nikkei 225 rose 0.6 percent to 16,957.86 and South Korea's Kospi gained 0.9 percent to 1905.44. Australia's S&P/ASX 200 rose 0.4 percent to 5,323.50. Shares were also higher in Taiwan, New Zealand and Southeast Asia.

CHINA CURBS: The China Securities Regulatory Commission imposed curbs late Friday on margin financing, or borrowing to purchase stocks, following an investigation of the industry. The three affected brokerages, Citic Securities Co., Haitong Securities Co. and Guotai Junan, were forbidden to lend money and shares to new customers for three months after they allegedly were caught extending margin trading contracts in violation of the rules. The Shanghai Composite has surged almost 60 percent in the past year. The regulator's action has unnerved investors and might be a sign that authorities think the market has risen too much recently. Shares of Guotai Junan, one of the penalized brokerages, fell by the 10 percent daily limit.

Japan's central bank is not expected to make any major moves in a policy meeting that wraps up Wednesday.
