China’s Ministry of Finance said it supports allowing the central bank to trade government bonds, reaffirming a sentence from President Xi Jinping that ignited market speculation about a change of monetary strategy.

The ministry called for stepping up coordination between fiscal and monetary policy and “improving the mechanisms of base money injection and money supply adjustment,” in an article written by a study group and published by the People’s Daily on Tuesday. It was based on a recent book that compiled Xi’s statements about finance and economics.
