Amid escalating military tension along the Ukrainian border U.S. President Joe Biden is set to hold a video call with his Russian counterpart Vladimir Putin on Tuesday.
Biden is expected to warn of severe economic countermeasures if Moscow proceeds with an attack on Ukraine.
A senior U.S. administration official spoke to reporters about the call, but did not mention any details about possible measures that may be taken.
Local media had reported that these may include disconnecting Russia from the SWIFT international payment system used by banks around the world, however the White House has denied the report.
Currently, North Korea and Iran have been sanctioned in this way.
The warning comes as tens of thousands of Russian troops have been deployed along the Russia-Ukraine border.
However, on the same day, White House Press Secretary Jen Psaki stressed that a solution would be sought through "diplomatic means" first.
"I would say, our objective, or the president's objective is to on the front end, to always lead with diplomacy have those conversations. But in the meantime, to prepare a range of options."
Perhaps hinting at some options which could include transatlantic action, Psaki also stressed that the U.S. has been working with European allies to prepare strong countermeasures.
In fact, President Biden plans to speak with the leaders of Ukraine and several European allies ahead of his call with Putin, in an effort to keep a unified front.
The Kremlin says, Putin will ask for a guarantee that NATO will never expand into Ukraine or it will carry out attacks on it neighbor.
The U.S. State Department said the U.S. is committed to NATO's open door policy.
Ukraine, a former Soviet republic, now aspires to join the European Union and NATO.
