A U.N. delegation is in Haiti to evaluate international aid projects ahead of a new round of assistance for the troubled country.

The U.N. Economic and Social Council delegation is studying how well aid groups and the government coordinate their efforts amid criticism that some projects conflict or overlap. The eight-member team arrived Monday.

The four-day visit follows pledges of $324 million in new aid last month by the U.S., Japan, Canada and other donors.

Haiti's crippling poverty was worsened last year by four storms that caused $1 billion in damage.
