The Group of 20 rich and developing countries are expected to commit to further efforts to boost growth after holding talks here Saturday, despite fledging signs of an economic recovery. The G-20 nations are also likely to pledge restrictions on excessive bankers' pay in a bid to address concerns about the risk-promoting bonus culture blamed for fueling the current crisis although they are expected to stop short of some of the tougher measures wanted by European governments. "We meet at a critical juncture for co-operation in the global economy ," Brown told officials from countries representing 80 percent of the world's output at the start of talks on Saturday. "The G-20 needs to agree a clear and unambiguous mandate for the G-20 to give priority to the resumption of global growth and to help countries achieve sustainable growth going forward," he added.
