MOSCOW President Vladimir V. Putin said on Thursday that he would sign into law a bill banning the adoption of Russian children by American citizens, retaliating against an American law that punishes Russians accused of violating human rights and dealing a potentially grave setback to bilateral relations.
Mr. Putin announced his decision at a meeting with senior government officials, including cabinet members and legislative leaders. The adoption ban, included in a broader law aimed at retaliating against the United States, was approved unanimously by the Federation Council, the upper chamber of Parliament, on Wednesday.
Mr. Putin also said he would sign a decree calling for improvements in Russia’s deeply troubled child welfare system that the Federation Council also adopted Wednesday. “I intend to sign the law,” Mr. Putin said, “as well as a presidential decree changing the procedure of helping orphaned children, children left without parental care, and especially children who are in a disadvantageous situation due to their health problems.”
United States officials have strongly criticized the measure and have urged the Russian government not to enmesh orphaned children in politics.
“It is misguided to link the fate of children to unrelated political considerations,” a State Department spokesman, Patrick Ventrell, said on Wednesday before Mr. Putin announced his decision.
Internally, however, Obama administration officials have been debating how strongly to respond to the adoption ban, and are trying to assess the potential implications for other aspects of the relationship with Russia. The United States, for example, now relies heavily on overland routes through Russia to ship supplies to military units in Afghanistan, and has enlisted Russia’s help in containing Iran’s nuclear program. The former cold war rivals also have sharp disagreements, notably over the civil war in Syria.
Until Thursday, these larger considerations, along with the possibility that Mr. Putin might veto the adoption bill, seemed to forestall a more forceful response from Washington.
The ban is set to take effect on Tuesday, and some senior officials in Moscow said they expected it to have the immediate effect of blocking the departure of 46 children whose adoptions by American parents were nearly completed. Adoption agency officials in the United States who work regularly with Russian orphanages said they expected the number of families immediately affected by the ban to be far larger, about 200 to 250 who have already identified a child that they planned to adopt.
Since Mr. Putin returned to the presidency in May, Russian officials have used a juggernaut of legislation and executive decisions to curtail the United States’ influence and involvement in Russia, undoing major partnerships that began after the fall of the Soviet Union.
The adoption ban, however, is the first step to take direct aim at the American public and would effectively undo a bilateral agreement on international adoptions that was ratified this year and took effect Nov. 1. That agreement called for heightened oversight in response to several high-profile cases of abuse and deaths of adopted Russian children in the United States.
About 1,000 Russian children were adopted in 2011 by parents from the United States, which leads in adoptions here, and more than 45,000 such children have been adopted by American parents since 1999.
Pavel A. Astakhov, Russia’s child rights commissioner and a major proponent of the ban, said the 46 pending adoptions would be blocked regardless of previous agreements, and he expressed no regrets over the likely emotional turmoil for the families involved.
“The children who have been chosen by foreign American parents — we know of 46 children who were seen, whose paperwork was processed, who came in the sights of American agencies,” Mr. Astakhov said in his statement. “They will not be able to go to America, to those who wanted to see them as their adopted children. There is no need to go out and make a tragedy out of it.”
