Moscow , Russia ( CNN ) -- Artyem Saveliev turns eight years old this week . His birthday will be anything but normal . Last Thursday his American adoptive family put him on a solo , trans-Atlantic flight from the United States to Moscow . They hired a Russian driver to deliver the boy from the airport to the Russian Ministry of Education . Russian officials allowed CNN to see a copy of a letter addressed to the Ministry of Education and signed by Artyem 's adoptive mother , Torry Hansen , which the little boy carried when he arrived . `` To Whom It May Concern , '' the letter reads , `` This child is mentally unstable . He is violent and has severe psychopathic issues/behaviors . I was lied to and misled by the Russian Orphanage workers and director regarding his mental stability ... After giving my best to this child , I am sorry to say that for the safety of my family , friends and myself , I no longer wish to parent this child . As he is a Russian National , I am returning him to your guardianship and would like the adoption disannulled [ sic ] . '' Russian officials are fuming at these accusations . `` How can you imagine that a 7-year-old boy can be [ a ] menace or danger for the family ? For the adult people ? '' said Pavel Astakhov , Russia 's Child Rights Ombudsmen . `` [ Artyem ] is in very good mental and physical condition , '' Astakhov said . `` He 's a very nice boy . He 's funny . And he 's very communicative . '' Astakhov met with Artyem several times since he arrived in Moscow , as have officials from the U.S. Embassy . `` When we saw him , he looked like a very tired little boy off a long trans-Atlantic flight , '' said John Beyrle , the U.S. ambassador in Moscow . The case of Artyem comes after the Russian media focused intense attention on several previous cases in recent years of abuse involving adopted Russian children in the United States . Not surprisingly , some Russians are calling for an end to the practice of foreign adoption . `` I am against the idea of sending our children abroad , '' said a woman , who gave her name only as Alexandra , as she watched her grandchildren play on a sunny day in a Moscow park . Russian officials have made public appeals for a temporary freeze of American adoption of Russian children until a proposed bilateral treaty has been signed to allow monitoring of children after they are brought to the United States . `` We do n't have any instrument or tools to control our children which are living in adoptive families , '' said Astakhov . `` In this situation we have a kind of legal vacuum ... we have to freeze all activity in the adoptive process for the United States of America . '' Those are ominous words for thousands of desperate American families who end up waiting years and spending tens of thousands of dollars trying to adopt Russian children . According to the U.S. Embassy in Moscow , more then 50,000 Russian children have been adopted by American families in the last 16 years . The U.S. State Department offered to send a delegation of diplomats to Moscow later this month to address the adoption issue . `` The Russian government has now told us informally that that 's acceptable . We 're actually working out the dates , '' said Beyrle . `` So I would say to American families that are in the process of adoption not to worry too much . We 're working on this , and we really do n't think that this will have any long-term effect on the ability of American families to adopt here . '' Russia has no shortage of orphans . The United Nations Children Fund reported that in 2008 , some 714,000 Russian children were living in state institutions . Unlike many Western societies , the vast majority -- 83 percent of these children -- are `` social orphans '' taken from biological parents who were deemed unfit by Russian state agencies , said Bertram Beinvel , UNICEF 's representative in Moscow . `` What is important to draw out of this [ Artyem 's ] case is to conduct a thorough analysis on the adoption of the child , then to [ learn ] what happened when he was put back on the plane , '' Beinvel said . He also called for a bilateral treaty to prevent future cases of abuse from occurring . Both U.S. and Russian officials predicted it might take a matter of months to hammer out this proposed agreement . But that offers little consolation to Artyem Saveliev , who has now lost two families before reaching the age of 8 . `` He lost his native family , his mother . And he lost his adoptive family , Torry Hansen , '' said Astakhov . `` Now the best way is to place him in a new family which can give him attention and love . '' But Astakhov made it clear any new family for Artyem would be a Russian one .
