On Wednesday US state department spokeswoman Heather Nauert said it had been determined that Russian Federation "has used chemical or biological weapons in violation of global law, or has used lethal chemical or biological weapons against its own nationals".
Those sanctions will include the presumed denial of export licenses for Russian Federation to purchase many items with national security implications, according to a senior State Department official who briefed reporters on condition of anonymity as he was not authorised to do so by name. These are sensitive goods that normally would go through a case-by-case review before they are exported.
Earlier this month, a group of senators led by Lindsey Graham introduced a new bill proposing further sanctions against Russia-the latest in what is turning into a string of Russia-sanction legislative efforts-this time focusing on investments in energy projects outside of Russian Federation that Russia's government supports. The statement also accused Russian Federation of violating global law.
"Russia has repeatedly warned that talking to us from a position of strength, and in the language of ultimatums, is futile and pointless", she said.

Distrust between the two countries has spiked amid Russia's renewed aggressiveness on the world stage, starting with the annexation of Crimea in 2014 and Moscow's subsequent interference in the 2016 USA presidential election.

Russian Federation has criticised the new United States sanctions as "draconian".
Vladimir Putin has ordered that a proposal to raise 500 billion roubles ($7.5 billion) a year from metal and mining firms be looked at, but the Russian president has not decided whether to approve the plan by a Kremlin economic aide.
The Government has welcomed new U.S. sanctions on Russian Federation for using a military grade nerve agent on a former spy in Salisbury.
Britain said it welcomed the United States response to the chemical attack in Salisbury, the sleepy English town where the Skripals were poisoned. With these sanctions, the exports will be presumptively denied.
