Finance ministers are considering how to start winding down trillions of dollars in government stimulus funds that have saved the world's economies from collapse.

Economic officials from the Group of 20 industrialized nations are meeting in London Friday and Saturday to discuss this and other issues ahead of the G-20 summit in the United States later this month.

G-20 governments are calling for a coordinated exit from the emergency stimulus measures.

Finance ministers in London this week also are expected to support actions to reduce bonuses paid to bankers.

Swedish Finance Minister Anders Borg said Wednesday the "bonus culture must come to an end."

Critics say these bonuses encourage risky bets that hurt companies and the economy and were a key reason the economic crisis grew so bad so quickly.
