"The Foreign Ministry has already started consultations with foreign partners over the implementation of the law. Not all of the lists approved so far are made public and they differ in content, but we will, of course, build on the experience of our partners," Rasa Jakilaitienė the foreign minister's spokeswoman, told BNS.
The ministers for foreign and interior affairs are responsible for compiling the "blacklist". The law, based on which it will be compiled, will come into force next year.
Gabrielius Landsbergis, the leader of the conservative Homeland Union–Lithuanian Christian Democrats, has proposed a list of 44 Russians, including Alexander Bastrykin, the head of Russia's Investigative Committee, and Andrei Lugovoy, a lawmaker.
Lithuania became the fifth country -- after the United States, Canada Britain and Estonia -- to adopt legislation named after Russian lawyer Sergei Magnitsky, who died in a Russian after uncovering a corruption scheme. Magnitsky's supporters say that he was unjustly accused and did not receive appropriate medical care in prison.
Russia has said it will retaliate by barring entry to a group of Lithuanian citizens.
