MOSCOW — President Vladimir V. Putin’s decision on Thursday to enact a ban on the adoption of Russian children by American citizens dealt a serious blow to an already strained diplomatic relationship, but for hundreds of Americans enmeshed in the costly, complicated adoption process, the impact was deeply personal.
“I’m a little numb,” said Maria Drewinsky, a massage therapist from Sea Cliff, N.Y., who was in the final stages of adopting a 5-year-old boy named Alyosha. Both she and her husband have flown twice to visit him, and they speak to him weekly on the telephone. “We have clothes and a bedroom all set up for him, and we talk about him all the time as our son.”
But the couple fear that Alyosha may never get to New York, after Mr. Putin’s announcement Thursday that he would sign the adoption ban into law, as part of a bill retaliating against a new American law aimed at punishing human rights abuses in Russia.
The law, which Mr. Putin signed on Friday, calls for the ban to be put in force on Tuesday, and stands to upend the plans of many American families in the final stages of adopting in Russia. Already, it has added wrenching emotional tumult to a process that can cost $50,000 or more, requires repeated trips overseas, and typically entails lengthy and maddening encounters with bureaucracy. The ban would apparently also nullify an agreement on adoptions between Russia and the United States that was ratified this year and went into effect on Nov. 1.
The bill was approved unanimously by the Federation Council, the upper chamber of Parliament, on Wednesday. Mr. Putin said that he would sign it as well as a resolution also adopted Wednesday that calls for improvements in Russia’s child welfare system. “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.”
Mr. Putin also brushed aside criticism that the law would deny some Russian orphans the chance for a much better life in the United States. In 2011, about 1,000 Russian children were adopted by Americans, more than any other foreign country, but still a tiny number given that nearly 120,000 children in Russia are eligible for adoption.
“There are probably many places in the world where living standards are better than ours,” Mr. Putin said. “So what? Shall we send all children there, or move there ourselves?”
United States officials have strongly criticized the measure and have urged the Russian government not to entangle orphaned children in politics. “We have repeatedly made clear, both in private and in public, our deep concerns about the bill passed by the Russian Parliament,” a State Department spokesman, Patrick Ventrell, said Thursday.
Internally, however, Obama administration officials have been debating how strongly to respond to the adoption ban, and the potential implications for other aspects of the country’s relationship with Russia.
The United States relies heavily on overland routes through Russia to ship supplies to military units in Afghanistan, and it 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.
The bill that includes the adoption ban was drafted in response to the Magnitsky Act, a law signed by President Obama this month that will bar Russian citizens accused of violating human rights from traveling to the United States and from owning real estate or other assets there. The Obama administration had opposed the Magnitsky legislation, fearing diplomatic retaliation, but members of Congress were eager to press Russia over human rights abuses and tied the bill to another measure granting Russia new status as a full trading partner.
Mr. Putin loudly accused the United States of hypocrisy, noting human rights abuses in Iraq, Afghanistan and at Guantánamo Bay, Cuba, and he pledged to retaliate. But he held his cards even as the lower house of Parliament, the State Duma, approved the adoption bill by a large margin, followed by unanimous approval by the Federation Council.
Although his decision has been eagerly awaited, Mr. Putin seemed blasé at a meeting with senior government officials on Thursday. When Vladimir S. Gruzdev, the governor of the Tula region, said, “I would like to ask: What is the fate of the law?” Mr. Putin replied, “Which law?”
