"That is what you are seeing all around the world, starting from Wall Street. People are showing their frustrations by trying to send a very clear and unambiguous message to the world," Ban said.
He asked world leaders to use the upcoming G-20 summit in Cannes to find solutions for the entire global economy and not focus merely on domestic financial concerns.
In a message to the G-20 leaders, Ban said "business-as-usual or just looking at their own domestic economic issues will not give any an swers to the current very serious international economic crisis."
The G-20 leaders have a very "broad and important, crucial, responsibility to perform...towards the global economy," Ban, currently on a visit to Switzerland, told reporters there yesterday.
He said leaders of the developed and emerging economies should restore confidence and trust of the people and come out with a broader perspective to tackle the economic crisis.
He said the G-20 nations make up 80 per cent of the world's GDP and 85 per cent of the world's population.
"We have to really address this issue with a sense of flexibility and compromise, and come out with actionable plans," he said.
The G-20 summit will be held on November 3-4 in Cannes, France.
