Financial and Central bank leaders have started to hammer out a joint communique ahead of the G20 summit. Officials say consensus is needed on using monetary and fiscal policies and structural reforms.

China's deputy finance minister, Zhu Guangyao, said  the point was raised to strengthen communication on foreign exchange policies. He said G20 members had agreed not to lower their currencies to gain trade benefits.

The G20 coordinator meeting will then start on Thursday. Together with the finance and central bank deputies' meeting, these will lay the groundwork for the following days' agenda.
