China's central bank governor Zhou Xiaochuan warned on Sunday that the country needs to be vigilant for signs of deflation and said policymakers were watching slowing global economic growth and declining commodity prices.
"Inflation in China is also declining. We need to have vigilance if this can go further to reach some sort of deflation or not," Zhou said at a high-level forum in Boao, on the southern Chinese island of Hainan.
Last week, Zhou said China could undermine structural reforms if it adopts an excessively loose monetary policy, while pledging to relax capital controls to help make the yuan currency fully convertible.
The People's Bank of China (PBOC) has cut interest rates twice since November and taken other steps to support the cooling economy. Economists believe it will be forced to take more aggressive easing measures in the coming months if prices and the economy continue to weaken.
At an annual parliamentary meeting that began earlier this month, China announced an economic growth target of around 7 percent for this year, down from 7.4 percent in 2014, already the slowest in 24 years.
In late February, the central bank's newspaper warned that China is dangerously close to slipping into deflation, highlighting increasing nervousness in policymaking circles.

Producer prices declined 4.8 percent in February, the sharpest drop since October 2009 and extending a long-running factory deflation cycle to nearly three years.
