Germany, China, Brazil and South Africa have criticised US plans to pump $600bn (£373bn) into the US economy.

German Finance Minister Wolfgang Schaeuble said the US policy was "clueless" and would create "extra problems for the world".

The US Federal Reserve could weaken the US dollar and hurt exports to America.

China's Central Bank head Zhou Xiaochuan urged global currency reforms, while South Africa said developing countries would suffer most.
