Although the financial and economic crisis has affected all countries, it is important to take into account the varying impacts and challenges of the crisis on the different categories of developing countries. The crisis is further endangering the achievement of their national development objectives, as well as the internationally agreed development goals, including the Millennium Development Goals. We are particularly concerned about the impact on countries in special situations, including least developed countries, small island developing States and landlocked developing countries, and on African countries and countries emerging from conflict. We are equally concerned about the specific development challenges of middle-income countries and low-income countries with vulnerable and poor populations. For all these countries, the crisis presents unique challenges to their efforts to achieve their national development goals. Our collective responses to this crisis must be made with sensitivity to the specific needs of these different categories of developing countries, which include trade and market access, access to adequate financing and concessionary financing, capacity-building, strengthened support for sustainable development, financial and technical assistance, debt sustainability, trade facilitation measures, infrastructure development, peace and security, the Millennium Development Goals, and our previous international development commitments.
