The global push for tougher financial regulation has come under the spotlight at the World Economic Forum.
Top US and European bankers have held behind-the-scenes talks, but they are said to be at odds on strategy.
Some say it is time to stop the blame game over the financial crisis.

Some 2,500 people are taking part in the annual five day meeting in Davos in Switzerland.
They include chief executives, national and regional government officials, as well as the leaders of NGOs and unions.
