TOKYO — Asian stock markets mostly dropped Wednesday as China's surprise interest rate hike raised fears that Chinese growth will slow, weighing on the global recovery.

The hike to the key rate, announced Tuesday, was the first for China since 2007 as it tries to control inflation and guide growth to a more sustainable level rather than revving up the economy. China's economy grew 10.3 percent in the second quarter.

The downdraft in Asian markets followed falls on Wall Street and in Europe. Oil rose above $80 a barrel after the China news dragged it down more than 4 percent the previous day.

"China's announcement was a big surprise for the market. Sentiment dampened across Asia as investors worried that a hike in interest rates could pressure China's economic growth," said Masatoshi Sato, market analyst at Mizuho Investors Securities Co. Ltd.
