Hong Kong shares, which were up on Thursday after the U.S. central bank signalled it was not in a rush to raise interest rates, were also softer. The Hang Seng index dropped 0.3 percent, while the Hong Kong China Enterprises Index lost 0.1 percent.

ChiNext is up 47 percent this year and currently trades at 85 times companies' earnings, while China's main stock indexes have hit near seven-year highs.
