American officials sought to water down the resolution by removing language that called on governments to “protect, promote and support breast-feeding” and another passage that called on policymakers to restrict the promotion of food products that many experts say can have deleterious effects on young children. 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.
