The spokeswoman noted that the U.S. reserves the opportunity and resources for additional sanctions, noting that "a piece of paper is just a piece of paper until it's implemented," and warning that there was evidence that Russia was continuing to take "aggressive actions."
She did not specify the terms and conditions under which Washington would resort to using the power levers. She said that there was a long way ahead, and the U.S. did not expect all of the agreements to be implemented in the next few days, though expressing hope that this would be done quickly.
Psaki also touched on the matter of the Crimean peninsula, annexed by Russia, stating that the U.S. believes Crimea to be a part of Ukraine.
Commenting on the possibility of a decision by the U.S. president to provide Ukraine with weapons, Psaki noted that all issues remain on the table and discussions continue. She stressed that Washington hoped that the agreement on withdrawal of troops and heavy weapons will be implemented, but the debate (on weapons for Ukraine. - ed.) continues in the United States and with European partners.
