ST. ANDREWS, Scotland - Finance officials from rich and developing countries have pledged to maintain emergency support for their economies until global recovery is assured.

Saturday's statement from the Group of 20 countries in Scotland says that economic and financial conditions have improved.

But the statement stresses that recovery is "uneven and remains dependent on policy support." High unemployment remains a major concern.

The G-20 finance ministers and central bankers also commit to take action to tackle the threat of climate change and work towards "an ambitious outcome" at a major UN conference in Copenhagen next month.

Officials are considering financial help for poorer countries to develop green technology.
