More than $1.35 billion has been committed to Haiti in humanitarian assistance since the devastating earthquake on Jan. 12, but less than $23 million in cash has been given to the Haitian government so far, leaving President Rene Preval beleaguered and wary about the reconstruction. Preval will be at the United Nations on Wednesday to present a reconstruction plan to an international donor conference, with the United States orchestrating an attempt to get 120 nations to commit to nearly $4 billion to rebuild Haiti. Haiti and the donors have yet to agree to a plan on how that money will be disbursed, but a major element is a request for $350 million for the government for the rest of this year. 'The budget support is fundamental,' said Robert B. Zoellick, president of the World Bank, noting that many donors had resisted this kind of assistance in the past out of concerns over corruption and the government's ability to carry out projects. Major international donors and the Haitian government itself have said that the rebuilding presented an opportunity to try to break the traditional cycle in which donors finance projects through nongovernmental organizations, bypassing the government. Too many donors decide what Haiti needs and then find someone to make it happen, Haitian officials said. 'In the end, the government has nothing to do with it,' said Gabriel Verret, a senior economic adviser to Preval. 'That is the frustration.' To ensure that the government gets to play a role, there are plans to create an interim reconstruction commission, with both donors and the Haitian government signing off on projects and expenditures. The government said Tuesday that the interim commission would be led by Preval and former President Bill Clinton. (There has been a certain amount of grumbling around the United Nations about tight control by the State Department over the donor conference, with a senior European diplomat calling it 'The Bill and Hillary Show.') U.N. diplomats said that in private the Obama administration and Haitian officials were still wrangling over the degree of involvement of Haitian government ministries in the reconstruction. 'Preval has been saying, 'Wait, why should we build this parallel structure here?'' said a U.N. diplomat, who spoke on the condition of anonymity because of the delicate nature of the discussions. He said that the United States was pushing for the commission as a quicker, faster way to rebuild. In January, the United States offered to meet the payroll of the Haitian police, but insisted on issuing the checks. After the Haitian government realized that its police officers would know they were being paid by the American government, it declined the offer and found the money elsewhere, U.N. diplomats said.
