When that failed, they turned to threats, according to diplomats and government officials who took part in the discussions. Ecuador, which had planned to introduce the measure, was the first to find itself in the cross hairs.The Americans were blunt: If Ecuador refused to drop the resolution, Washington would unleash punishing trade measures and withdraw crucial military aid. The Ecuadorean government quickly acquiesced.
The showdown over the issue was recounted by more than a dozen participants from several countries, many of whom requested anonymity because they feared retaliation from the United States.
Health advocates scrambled to find another sponsor for the resolution, but at least a dozen countries, most of them poor nations in Africa and Latin America, backed off, citing fears of retaliation, according to officials from Uruguay, Mexico and the United States.
“We were astonished, appalled and also saddened,” said Patti Rundall, the policy director of the British advocacy group Baby Milk Action, who has attended meetings of the assembly, the decision-making body of the World Health Organization, since the late 1980s.
During the deliberations, some American delegates even suggested the United States might cut its contribution to the W.H.O., several negotiators said. Washington is the single largest contributor to the health organization, providing $845 million, or roughly 15 percent of its budget, last year.
The confrontation was the latest example of the Trump administration siding with corporate interests on numerous public health and environmental issues.
In talks to renegotiate the North American Free Trade Agreement, the Americans have been pushing for language that would limit the ability of Canada, Mexico and the United States to put warning labels on junk food and sugary beverages, according to a draft of the proposal reviewed by The New York Times.
During the same Geneva meeting where the breast-feeding resolution was debated, the United States succeeded in removing statements supporting soda taxes from a document that advises countries grappling with soaring rates of obesity.
The Americans also sought, unsuccessfully, to thwart a W.H.O. effort aimed at helping poor countries obtain access to lifesaving medicines. Washington, supporting the pharmaceutical industry, has long resisted calls to modify patent laws as a way of increasing drug availability in the developing world, but health advocates say the Trump administration has ratcheted up its opposition to such efforts.
The delegation’s actions in Geneva are in keeping with the tactics of an administration that has been upending alliances and long-established practices across a range of multilateral organizations, from the Paris climate accord to the Iran nuclear deal to Nafta.
Ilona Kickbusch, director of the Global Health Centre at the Graduate Institute of International and Development Studies in Geneva, said there was a growing fear that the Trump administration could cause lasting damage to international health institutions like the W.H.O. that have been vital in containing epidemics like Ebola and the rising death toll from diabetes and cardiovascular disease in the developing world.

The United States also insisted that the words “evidence-based” accompany references to long-established initiatives that promote breast-feeding, which critics described as a ploy that could be used to undermine programs that provide parents with feeding advice and support.
Elisabeth Sterken, director of the Infant Feeding Action Coalition in Canada, said four decades of research have established the importance of breast milk, which provides essential nutrients as well as hormones and antibodies that protect newborns against infectious disease.
A 2016 study in The Lancet found that universal breast-feeding would prevent 800,000 child deaths a year across the globe and yield $300 billion in savings from reduced health care costs and improved economic outcomes for those reared on breast milk.
Scientists are loath to carry out double-blind studies that would provide one group with breast milk and another with breast milk substitutes. “This kind of ‘evidence-based’ research would be ethically and morally unacceptable,” Ms. Sterken said.
Abbott Laboratories, the Chicago-based company that is one of the biggest players in the $70 billion baby food market, declined to comment.
Nestlé, the Switzerland-based food giant with significant operations in the United States, sought to distance itself from the threats against Ecuador and said the company would continue to support the international code on the marketing of breast milk substitutes, which calls on governments to regulate the inappropriate promotion of such products and to encourage breast-feeding.
In addition to the trade threats, Todd C. Chapman, the United States ambassador to Ecuador, suggested in meetings with officials in Quito, the Ecuadorean capital, that the Trump administration might also retaliate by withdrawing the military assistance it has been providing in northern Ecuador, a region wracked by violence spilling across the border from Colombia, according to an Ecuadorean government official who took part in the meeting.
The United States Embassy in Quito declined to make Mr. Chapman available for an interview.
“We were shocked because we didn’t understand how such a small matter like breast-feeding could provoke such a dramatic response,” said the Ecuadorean official, who asked not to be identified because she was afraid of losing her job.
