Will France lead the G20 to implement a tax on financial transactions that will aid developing countries and combat climate change?
French Finance Minister Christine Lagarde says Wednesday's meeting in Paris of finance ministers and central bank governors of 20 economies is not to dictate policy to other countries, but to establish a method to identify economic imbalances.
But she has also says the G20 will seek to prescribe policy reforms to countries that "diverge too much from the path of optimal growth for the international community".
Also on the agenda is the question of a financial tax, which Lagarde says the French presidency will propose "despite scant support from other members".
Economists and activists have questioned how effectively the French presidency of G20 will face up to the challenges.
