Russia's President Vladimir Putin has held the first major news conference of his third presidential term.
During the live, televised event, Putin said he would consider a ban on Americans being able to adopt Russian children, after Russian authorities were prevented from observing cases in the US where abuse against such children was alleged.
Referring to the new US law which denies entry to Russians suspected of human rights violations, Putin said: "The fact is, America has replaced one anti-Soviet, anti-Russian law - the Jackson-Vanick Amendment - with another, the Magnitsky Act.
Thirty demonstrators were arrested in Moscow during protests outside the Russian parliament as a bill that bans Americans from adopting Russian orphans was approved.
The measures counter American legislation - the so-called Magnitsky law - that targets Russians believed to have been involved in the death of lawyer Sergei Magnitsky while he was in custody.
It also bans non-profit Russian groups from receiving US funding, and was passed by an overwhelming majority, but there is some high-profile opposition.
Russia's foreign minister Sergei Lavrov told euronews: "If we put a stop to adoption, that means one thing: that we will have to revoke the agreement on international adoption with the United States. If we revoke it, we will no longer have any right legally to demand access to our children abroad. If only for that reason, I won't react so strongly.
The bill is expected to pass its final reading on Friday, but the Kremlin is well aware of possible long-term damage to already deteriorating relations with the US and there are some doubts about whether President Putin will sign it into law.
Russia's Foreign minister believes it's wrong to ban Americans from adopting Russian children, but said the U.S. should take responsibility for any that are sent there. The freeze could be part of Moscow's response to Washington's travel and financial restrictions on Russian officials, implicated in the death of lawyer Sergey Magnitsky in 2009.
