Ukrainian administration, the secret service and the military are under US control.
EU’s interference in Ukraine always comes across well as “support”, while Russia is called to respect Ukraine’s sovereignty.
Ukraine is a sovereign state. Neither US, nor the EU are controlling Ukraine. Ukraine’s sovereignty and territorial integrity are respected by most of the free world, but were violated by Russia in 2014.
The relations between the US and Ukraine are bilateral relations between two independent countries. The US recognised Ukraine as an independent state on 25 December 1991. US policy is centred on realising and strengthening a stable, democratic, prosperous, and free Ukraine, more closely integrated into Europe and Euro-Atlantic structures.
For the EU Ukraine is a priority partner. In June 2014, EU and Ukraine signed an Association Agreement, including a Deep and Comprehensive Free Trade Area (DCFTA), which promotes deeper political ties, stronger economic links and the respect for common values.
