The US ruling class is concerned that the Eurasian Economic Union is a reincarnation of the USSR. That is why the West started a war against the EAEU.
An escalation of the West-Russia relations resulted from the West’s intention to kill the EAEU in its cradle. It came right after Putin, Nazarbayev, and Lukashenka declared the establishment of the EAEU. A strong blow to the EAEU was the coup in Ukraine.
The EAEU will continue to be attacked. The use of disagreements between the EAEU countries, development of isolationism in Russia and Russophobic nationalism in other EAEU countries will be part of anti-EAEU activities.
This message is a conspiracy consistent with recurring pro-Kremlin narratives about West's anti-Russian activities and attempts to disrupt Russia's relations with allies as well as a coup d’état in Ukraine.
The escalation of West-Russia relations resulted from the Russian annexation of Crimea and Russia's destructive actions in Ukrainian Donbas and not from the West's attempt to kill the EAEU. The Council of the EU is clear in this respect: "Since March 2014, the EU has progressively imposed restrictive measures against Russia. The measures were adopted in response to the illegal annexation of Crimea and the deliberate destabilisation of Ukraine." Read more about the EU sanctions against Russia over the Ukraine crisis.
