PRAGUE, Feb 2 - IMF Managing Director Horst Koehler said on Monday that imbalances in the global current account remain a risk to economic recovery though a stronger euro and weaker dollar are helping facilitate a rebalancing. "The (world economic) recovery is broadening and deepening, with all major regions showing improvement," Koehler told a conference on euro entry for EU accession countries in Prague. "But we know that there are still risks, notably stemming from the persistent large global current account imbalances. So far, a stronger euro and correspondingly weaker US dollar are facilitating the needed global rebalancing of current accounts."//
