Investors were encouraged early in the day after the HSBC Purchasing Managers Index showed that China's manufacturing activity was improving. However, concerns on the sustainability of the recovery pulled Chinese stocks lower.

News from US overnight was positive as well. Official data had showed that new home sales in the world's largest economy jumped 5.7 percent to 389,000, the highest in more than two years.

Meanwhile, the Nikkei reported that the Bank of Japan will consider boosting its asset purchase programme by 10 tn yen at its upcoming policy meet, encouraging investors. The yen weakened against the dollar and the euro, sending exporters' stocks up.
