Asian stocks ended a choppy session mixed on Wednesday despite better-than-expected growth data from China.
The world's second largest economy grew 7.5 percent in the second quarter, above estimates for a 7.4 percent increase. Meanwhile, other data showed June industrial output rising a stronger-than-expected 9.2 percent on year and June retail sales increasing an annual 9 percent, in line with expectations.
"Overall, I think we're seeing the data bottoming out in the second-quarter and we think activity and growth will pick up in the second half of the year and China will be on track to meet the 7.5 percent growth target," said John Zhu, greater China economist at HSBC.
Sentiment in Asia was shaky following Federal Reserve Chair Janet Yellen's semi-annual testimony before the Senate Banking Committee on Tuesday. Yellen expressed concerns about stretched valuations in equity markets, including the social media and biotech sector, which saw U.S. markets finish mostly lower overnight.
