Committee Split Over Treaty to Ban Human Cloning The U.S. drive to enact a broad global ban on human cloning has suffered a severe setback at the United Nations. It also reveals a deep split within the world body on the cloning issue. The U.S. and Costa Rican proposal calling for drafting an anti-cloning treaty had nearly 50 co-sponsors, and was expected to pass easily. But it is fiercely opposed by many in the scientific community, who argue there is a need for therapeutic cloning for research and medical purposes. A rival resolution sponsored by Belgium and supported by Britain, France, and Germany, among others, would have banned only the cloning of babies. After the vote, Deputy U.S. Representative James Cunningham said he was disappointed that countries opposing a total ban had used a technicality to derail the will of a majority of the international community. It is particularly regrettable that it was by a margin of only one vote that we will be prevented from formally registering that more than 100 members of the Untied Nations favor the pursuit of the goal, of a total ban on human cloning, he said. |
