Governments have tried to squelch expectations the Group of 20 gathering of finance ministers and central bankers from the United States, China, Japan, Germany and other major rich and emerging economies will produce specific growth plans. But they face pressure to reassure nervous financial markets.
Christine Lagarde, the managing director of the International Monetary Fund, said governments should act faster on reforms promised at a G-20 meeting in 2014.
That list included some 800 commitments meant to simplify regulations and boost trade, investment and technology development, but many have yet to be carried out.
Referring to monetary and fiscal policy and structural reforms, Lagarde said, "There has to be action on all fronts."

Central banks still have room to use interest rate cuts and other stimulus but need governments to follow through with promised economic changes, said Mark Carney, head of the Bank of England.
"Global growth has disappointed because the innovation and ambition of global monetary policy has not been matched by structural measures," said Carney at the IIF event. "In most advanced economies, difficult structural reforms have been deferred."
"We are not lacking in policy proposals," he said. "We are lacking in policy implementation."
