European Union officials are preparing for a key summit in Brussels, where they will be trying to clinch a deal on how to tackle the eurozone debt crisis. The talks have been described by analysts as \"do-or-die\" for the 17 eurozone nations. Germany and France are pushing for new EU treaties, saying stricter fiscal rules should be enshrined there. Meanwhile, the European Central Bank is set to cut interest rates amid fears the eurozone is in recession, while ratings agency Standard & Poor\'s has said it will review the top AAA credit rating of the European Union for possible downgrade. At the same time, central banks in New Zealand and South Korea have kept interest rates on hold, citing fears of the impact of the debt crisis in Europe.
