The government will pay about $100 million for a fund proposed by United Nations Secretary General Kofi Annan to promote the international crusade against AIDS, government sources said Sunday.

The sources said Prime Minister Junichiro Koizumi, who has vowed to make "appropriate" financial contributions to the proposed fund, will announce the payment during his meeting with U.S. President George W. Bush later this month.

Japan will be the third major industrialized country to pledge financial contributions to the AIDS fund after the United States and France, the sources said.
