Japanese stocks extend losses after "tankan" data

HONG KONG (MarketWatch) -- Chinese stocks jumped to a seven-year closing high on Wednesday, ending above 3,800 for the first time since 2008, after two separate gauges of Chinese manufacturing activity in March both came in better than expected.

Mainland China's benchmark Shanghai Composite Index advanced 1.7% to 3,810.29, the highest settlement in more than seven years.

In Hong Kong, the Hang Seng Index rose 0.7% to 25,082.75, extending a three-session winning streak. The index marked its best close in nearly seven months.

Earlier in the day, China's official manufacturing Purchasing Managers Index rose to 50.1 in March from 49.9 in February, (http://www.marketwatch.com/story/chinas-official-manufacturing-pmi-rebounds-2015-03-31) back above the 50 mark dividing expansion from contraction. The result beat a forecast of a 49.8 gain in a Wall Street Journal survey.

On the same day, HSBC's final reading of China's manufacturing PMI for March was revised upward to 49.6, from a preliminary 49.2 (http://www.marketwatch.com/story/china-hsbc-manufacturing-pmi-shows-drop-2015-03-31), also ahead of market expectations.

In other Asian markets, Japanese stocks built on earlier losses after the Bank of Japan's quarterly "tankan" survey of Japan's big manufacturers showed (http://www.marketwatch.com/story/japans-tankan-sentiment-survey-shows-few-gains-2015-03-31) business sentiment barely changed, missing forecasts.

The Nikkei Average declined 0.9%, with the broader Topix also down 0.9%.

The yen (USDJPY) fell against the dollar to Yen120.27, compared with Yen120.14 late Tuesday in New York.

   Elsewhere, Seoul's Kospi Composite Index   lost 0.6%, and Sydney's S&P/ASX 200   dropped 0.5%.
