Japanese diplomats calculate that Japan's gross domestic product accounts for only 14.4 percent of the global economy. But Japan pays 19.5 percent of the United Nations budget, or almost $1 billion a year. By contrast, the United States accounts for 30 percent of world gross domestic product, but pays only 22 percent.
"Japan cannot just give sweet faces to everybody," Yukio Okamoto, chairman of the prime minister's Task Force on Foreign Relations, said in an interview here on Monday. "We have to question: Why are we the only country in the world with inflated cost on our shoulders?"
At the United Nations, Japanese officials say they are angry that the world body has failed them on two counts.
First, they say, United Nations diplomats were happy to have Japan pay one-fifth of the budget but were never moved to take the basic diplomatic step of removing a clause from the United Nations' founding charter that describes Japan as a "former enemy" nearly six decades after the end of World War II.
"The `enemy' clause ? no Japanese can understand why the U.N. continues such symbolism," Mr. Okamoto said.
