China will continue to broaden the permitted fluctuation range of yuan trading as the next step in deepening currency reform, a central bank official said on Tuesday.

"Market-oriented progress in interest rate and currency exchange rate reform will provide huge opportunities as well as challenges for the country's payment and settlement system," said Wang Yu, deputy director-general of the research bureau of the People's Bank of China.

She made the remarks while attending a forum in Beijing, without elaborating as to what extent and when the monetary authorities would make new adjustment to the range.
