The United States and its allies on Thursday imposed fresh sanctions on Russia, targeting dozens of Russian defense companies, hundreds of members of its parliament and the chief executive of the country's largest bank as Washington ramps up pressure on Moscow over its invasion of Ukraine.

The U.S. Treasury Department also issued guidance on its website warning that gold-related transactions involving Russia may be sanctionable by U.S. authorities, a move aimed at stopping Russia from evading existing sanctions.

"Our purpose here is to methodically remove the benefits and privileges Russia once enjoyed as a participant in the international economic order," a senior administration official said.

The United States and its allies have imposed several rounds of sanctions, including targeting the country's largest lenders and President Vladimir Putin, since Russian forces invaded Ukraine a month ago in the biggest assault on a European state since World War Two.

Moscow calls the assault a "special operation" to disarm and "denazify" its neighbor.

Among the new sanctions targets are more than 40 defense companies, including state-owned Tactical Missiles Corp and 28 firms to which it is linked, as well as its general director, the U.S. Treasury Department said in a statement.

The Treasury said Washington's action aligned with similar measures taken by the EU, the United Kingdom and Canada.

The Treasury said the conglomerate, which Britain has already hit with sanctions, produces naval systems and weapons that Russia is using against Ukraine, including the Kh-31, a high-speed airborne guided missile that has been employed extensively in Moscow’s offensive.

Other firms on the new list include manufacturers of ammunition for the Russian military, civilian and military helicopters, and drones that the Treasury said originally were designed for surveillance but have been "repurposed" and used to attack Ukrainian forces.

The Treasury also slapped sanctions on 328 members of the Duma, Russia's parliament, and Herman Gref, the head of Russia's largest lender, Sberbank, who the Treasury said was a close Putin associate.

The White House in a statement said Thursday's action also targeted 17 board members of Sovcombank and Gennady Timchenko, a longtime ally of Putin, his companies and family members.

The official said the United States warned Putin that it would face swift and severe consequences if he invaded Ukraine and they have delivered on that threat. The official noted that the country is facing punishing inflation and economic pain that will push it out of the world’s top 20 economies.

“Russia will soon face an acute shortage of ideas, talent and technology to compete in the 21st century, and Putin will be left with a strategic failure of his own making,” the official said.
