Trump’s adviser John Bolton said openly that sanctions introduced against Russia because of Ukraine did not concern Georgia. He actually said ”because of your problems we will not announce sanctions against Russia”. For America Russia is much more important than Georgia.
In fact, U.S. national-security adviser John Bolton said that Washington had taken "all necessary sanctions" against Russia related to the war it fought against Georgia in 2008. He emphasized that the United States supports Georgia's territorial integrity and independence.
In August 2017, the US adopted the Countering America’s Adversaries Through Sanctions Act, which refers also to the situation in Georgia and Russia's actions.
