BOAO, China--China's central bank Governor Zhou Xiaochuan warned on Sunday that continued monetary easing measures taken by other central banks could make the U.S. dollar "too strong" and cause capital to flow into the U.S. market.

Mr. Zhou, governor of the People's Bank of China, made the comments at a high-level economic and political forum in Boao, on the southern Chinese island of Hainan.

Mr. Zhou's remarks come amid growing worries about capital flowing out of emerging economies like China even as U.S. Federal Reserve is expected to raise interest rates later this year.

Central banks in Europe and Japan, on the other hand, have been relaxing monetary policy, while China also stepped up efforts to ease policy in recent months.

Also on Sunday, Mr. Zhou said that China has "more room" to ease monetary policy if inflation continues to fall and the slowdown in China's growth worsens. He said China will watch closely for signs of deflation amid falling global commodities prices.

Last week, he said China wouldn't relax monetary policy too aggressively for fear of undermining ongoing structural reforms.

In addition, Mr. Zhou said Beijing will press ahead with opening up its capital account as part of efforts to revamp the country's financial system.
