Euro zone leaders will likely achieve positive results at a weekend gathering on the debt crisis, European Council President Herman Van Rompuy said today. The finance ministers' meeting in Copenhagen on Friday is expected to mainly focus on whether to increase the size of a permanent bail-out fund from a planned €500 billion. "I'm confident that we will reach a positive outcome," Van Rompuy told a news conference after talks with South Korea's President Lee Myung-Bak. The International Monetary Fund has been pushing for an increase to as much as one trillion euros before it agrees to strengthen its own resources against a crisis. Adding to optimism ahead of the meeting are comments from German Chancellor Angela Merkel, who indicated she was prepared to allow a boost in the firewall, in an apparent shift of position amid fierce international pressure. Van Rompuy described a treaty signed earlier this month to control EU budgets as "a turning point in the crisis". European Commission President Jose Manuel Barosso also told the news conference he was "absolutely sure" the embattled European Union would emerge from the debt crisis stronger than before.
