Veto power is the only differentiator here or it becomes a game of numbers. The US and most of the other P-5 members have at various times expressed guarded support for expansion involving the G-4 states. The only noticeable exception was China, which opposes Japan and is ambiguous on India.
China's annual contribution [2010] to the UN for regular operations is $67,434,617. Japan pays $264,959,467. Germany pays $169,548,684. Spain pays $67,180,865. Canada pays $67,815,245. The Russian Federation pays $33,875,903. What's wrong with this picture?
The U.S. has been the largest financial supporter of the U.N. since the organization’s founding in 1945. The U.S. is currently assessed 22 percent of the U.N. regular budget and more than 27 percent of the U.N. peacekeeping budget. In dollar terms, the Administration’s budget for FY 2011 requested $516.3 million for the U.N. regular budget and more than $2.182 billion for the peacekeeping budget.
However, the U.S. also provides assessed financial contributions to other U.N. organizations and voluntary contributions to many more U.N. organizations. According to OMB, total U.S. contributions to the U.N. system were more than $6.347 billion in FY 2009. This is more than $1 billion more than total contributions as compiled by OMB for FY 2005, and it is indicative of the rising budgetary trends in the U.N. and the consequential demand on U.S. financial support.
