UNITED NATIONS — Under intense global pressure, the United States yesterday dropped its demand to amend a declaration reaffirming the U.N. blueprint to achieve equality for women, saying it was satisfied the document did not guarantee the right to abortion.

Chief U.S. delegate Ellen Sauerbrey, who was booed yesterday when she stated the U.S. position, said the U.S. would join in approving the declaration endorsing the 150-page platform for action adopted at the 1995 U.N. women's conference in Beijing.

The proposed U.S. amendment would have reaffirmed the Beijing platform and a declaration adopted with it — but only "while reaffirming that they do not create any new international human rights, and that they do not include the right to abortion."

But the United States found itself virtually alone, with nations from Africa, Europe, Latin America and Asia all opposed. Nilceia Freire, Brazil's minister of state for women's affairs, said not a single country supported a revised amendment the United States offered Thursday and that every speaker had insisted that the declaration be left untouched.

Sauerbrey drew boos from the audience, which included some of the 6,000 activists who came from around the world.

The loudest catcalls came when she articulated U.S. policy on AIDS prevention for adolescents: "We emphasize the value of the ABC — abstinence, be faithful, and correct and consistent condom use where appropriate — approach in comprehensive strategies to combat the spread of HIV/AIDS and the promotion of abstinence as the healthiest and most responsible choice for adolescents."

The attempt to amend the one-page declaration had overshadowed the start of a two-week review of the Beijing platform that began Monday, angering many of the 130 governments and 6,000 representatives of women's and human-rights organizations. They had hoped to focus on obstacles to women's equality in the economy, the family, education and political life.

Sauerbrey said the United States sought to amend the declaration because of concerns that advocacy groups were attempting to hijack the term "reproductive health services" in the document and define it in a way that guarantees the right to abortion.

Alexandra Arriaga, director of government relations at Amnesty International USA, said the U.S. decision "reaffirms that women's rights are human rights."
