The amendments, which are set to be voted on Wednesday, came after the Russian state-funded RT registered with the U.S. Justice Department as a foreign agent following pressure from the U.S. government.
U.S. intelligence agencies have alleged that RT served as a tool for the Kremlin to meddle in the 2016 U.S. presidential election. Russia has denied any interference.
The amendments under consideration in Russia were proposed by lawmakers in the State Duma, the lower house of the Russian legislature. Deputy Speaker Pyotr Tolstoy said the revisions would give the Justice Ministry authority to register foreign media outlets as foreign agents.
Following the registration, the news outlets would be subject to requirements that already apply to foreign-funded non-governmental organization under a 2012 law on foreign agents.
The law requests all groups that receive foreign funding and engage in vaguely defined political activities to register as foreign agents. Critics of the law have said the definition of political activity is so loose that it could be used against almost any non-governmental organization.
The law was approved after a slew of massive anti-Kremlin protests in Moscow in 2011-2012. President Vladimir Putin accused the U.S. of instigating them.
At the same time, Putin has harshly criticized the U.S. demand regarding the RT channel as an attack on freedom of speech. He said Russia would retaliate.
The amendments to cover non-Russian media outlets are on a rapid course. The State Duma is set to approve them on Wednesday. They would then go pass quickly to the upper house and then to Putin for signing.
It wasn't immediately clear how the proposed amendments would be applied.
They are broadly phrased to allow the government to declare practically any foreign media outlet as a foreign agent. But Russian officials and lawmakers emphasized Tuesday that they would take a measured approach, one strictly proportionate to the U.S. action.
Leonid Levin, head of the Duma's committee for information, emphasized that the amendments were a framework intended to provide a legal basis for government action.
"It will up to the Justice Ministry to decide whom to list as foreign agents," Levin said. "I expect the amendments to be applied strictly quid pro quo in response to the moves against Russian media."
Andrei Klimov, the head of a panel established by the upper house of the Russian parliament to investigate alleged foreign interference in Russian affairs, also said the Russian government's application of the foreign media rules would be selective and mirror actions by the United States.
At the same time, Klimov kept the door open for broader restrictions in the future, saying lawmakers will ponder prospective legislation to restrict foreign nationals' involvement in Russia's affairs.
Legislation to be drafted next year could define the status of foreigners involved in "undesirable activities" in Russia, as well as Russians engaging in "undesirable cooperation" with them, Klimov said.
The Committee to Protect Journalists, a New York-based independent press freedom watchdog, criticized the U.S. Department of Justice order for the RT to register as a foreign agent as a "bad idea."
"This is a shift in how the law has been applied in recent decades, so we have little information about how its reporting requirements might affect individual journalists," CPJ North America Program Coordinator Alexandra Ellerbeck said. "We're uncomfortable with governments deciding what constitutes journalism or propaganda."
At the same time, the Committee to Protect Journalists urged Russia not to take retaliatory steps.
"It's outrageous that the Russian government, which has attacked, undermined, and stifled independent media, and failed to properly investigate the murders of leading independent journalists in the country, is now threatening measures to curtail the work of international media organizations," CPJ Europe and Central Asia Program Coordinator Nina Ognianova said in a statement.
Ognianova added that while the U.S. move on RT was "ill-advised," Russia also would be amiss "to use it as a pretext to justify punitive action."
