The US has imposed new sanctions on Russian oligarchs, including President Vladimir Putin's son-in-law, and several entities accused of supporting and profiting from the Russian government's efforts to undermine western democracies.
The U.S. Treasury Department imposed sanctions on 15 of the largest Russian businesses, as well as 24 Russian officials and individual business leaders.
The Turkish Foreign Ministry has confirmed that Ankara's stance on the delivery of Russian S-400 missile defense systems to Turkey hasn't changed despite Washington's sanctions against the Russian state arms exporter Rosoboronexport.
In all, President Donald Trump's administration targeted seven oligarchs, 12 companies they own or control, 17 senior Russian officials and a state-owned arms export company.
The president has also repeatedly slammed the Mueller probe into Russian meddling in the 2016 election as a "witch hunt" and a "hoax".More news: Raikkonen on top for dominant Ferrari in Bahrain practice
The sanctions freeze any assets that those targeted have in United States jurisdictions and bars Americans from doing business with them.
But Congress persisted, backed by evidence from U.S. intelligence agencies, and in March the administration finally imposed sanctions on 19 Russian entities for "malicious cyber attacks".
The speaker of Russia's State Duma lower parliament, Vyacheslav Volodin, said the sanctions "aimed to weaken Russian Federation and its economy".
The move comes after 60 American diplomats left Russia as part of tit-for-tat series of expulsions following the poisoning of a Russian spy and his daughter in Britain, allegedly at the hands of the Kremlin.
"The Russian government operates for the disproportionate benefit of oligarchs", he added.
Numerous targets are individuals and businesses associated with Russia's energy sector, including those affiliated with state-owned Gazprom.More news: Mariners' James Paxton, eagle landing perch, was just 'trying not to panic'
So far Mueller has indicted 19 people, including 13 Russians, and reports suggest he may soon ask to interview Trump himself.
"The requisitioning of private property and other people's money is known as theft", the ministry added.
Moscow said the new United States restrictions will be faced with "a firm response", urging Washington to "swiftly give up on the illusion that one can communicate with [Russia] using the language of sanctions".
"Washington has delivered yet another blow on the Russian-US relations".
The oligarchs were not immediately sanctioned then, but the existence of the list - and a more detailed classified annex - created uncertainty over global business dealings with some Russian sectors.
In January the US Treasury published the controversial Kremlin List, which was shrugged off by the market and widely criticized as "one size fits all" document copy-pasted from the rankings of Russia's richest published by Forbes magazine.More news: EK and Steve Kyler Discuss Kyrie Irving's Injury
"This is an attempt to use the tools (sanctions) to justify the absence of a real strategy and justify the alleged legitimacy of its actions against Russian Federation".
