Asia Ends Mixed; China Stocks Hit 1-Week High

The Shanghai Composite rallied over 1 percent on Thursday as investors cheered news of easing regulations while Japan's Nikkei index closed off its five-and-a-half year peak after data showed that capital spending fell for a fifth straight month.

The Nikkei finished above 15,000 after losing as much as 1 percent during the session and Sydney's S&P ASX 200 fell below the 5,200 mark.

Amid out-performers, the Kospi closed 5 points shy from a one-month high and Shanghai stocks outperformed to hit a one-week high.
