联合国长期以来受经费问题困牡美国多年来一直艳欠应向联合国缴纳的会费(包括正常预算的分摊会费及维和行动的分摊会费).则使这一问题雪上加霜。大国关系斗争制约相对稳定,地区性国家在相互靠拢;地区性冲突和大国卷入交织,但冲突的次数和规模都在缩小;世界军备下降不平衡,质量建军成为主要竞争形势。 This problem has been exacerbated by the fact that the United Nations has long been hit by funding problems that the United States has been owed to the United Nations for many years, including assessed contributions to the regular budget and assessed contributions to peacekeeping operations. The struggle between big powers relations is relatively stable. Regional countries are moving closer to each other. Regional conflicts and big powers are intertwined. However, the number and scale of conflicts are narrowing. The world arms imbalance and quality army building have become the main competitive situations.
