Now the Kremlin has confirmed it is working on retaliatory measures to hit back at the Trump administration.
Russia’s Transport Minister Maxim Sokolov confirmed the news.
He said: “I will not announce anything, we are working on that.”
It considered measures such as banning imports of US agricultural, alcoholic, and tobacco products as well as medical drugs.
However, Mr Sokolov’s announcement is a direct indication Putin’s government are actively considering how to react.
Relations between Washington DC and Moscow have nosedived since the poisoning of ex-Russian spy Sergei Skripal on UK soil.
Supporting the UK’s view that the Kremlin was responsible for the attack, Trump expelled dozens of diplomats from the US.
However, diplomatic relations have deteriorated further since then after the US, UK and France launched airstrikes on Syrian military bases in the early hours of Saturday morning.
Military action was taken against the Barzah Research and Development Centre outside Damascus with 76 missiles and what the US military described as the Him Shinshar Chemical Weapons Complex outside the city of Homs.
The strikes were an act of retaliation after an alleged chemical attack by the Assad regime on Syrian civilians a week ago.
However, both the Syrian government and Russia deny any incident took place.
Russia sent a grave warning to the US ahead of the military intervention and warned Trump not to go ahead with the attacks.
Putin is yet to announce how he will respond to the airstrikes going ahead.
