Finance chiefs from the world's twenty industrialized and fastest developing nations will discuss at a meeting in Paris how to steady the world economy.
French finance minister Christine Lagarde has the difficult task of picking up the pieces of last November's Group of 20 summit of heads of state, which ended in Seoul without any meaningful agreement on how to defuse long-standing tensions over trade and currency imbalances.
Finding the right tools to measure these imbalances -- which many economists say contributed to the world's financial meltdown -- is the primary goal, Lagarde says.
She says the current system, whereby some countries like China save and export while others like the U.S. borrow and consume isn't sufficient.
The meeting takes place Friday and Saturday.
