The essence of the agreement between Yanukovych and Putin is much broader and complex than just some agreements that have been partially revealed to Ukraine and the world. The results of these agreements will be gradually implemented in the long-term strategic perspective until the creation of a single state entity under the complete domination of Russia and the gradual absorption of our state sovereignty.
What Yanukovych did on December 17, 2013 is much worse than simply joining the Customs Union. These were the first irreversible changes. Yanukovych no longer has the political freedom to make any independent decisions on the international arena. As of December 17, 2013, any steps by Ukraine towards Europe, including the signing of an association agreement between Ukraine and the EU, are impossible.
On December 17, 2013 Yanukovych annulled Ukraine as an independent entity, as a full-fledged participant in international politics, and put all international level decisions that concern Ukraine in the hands of Vladimir Putin.
It is also clear that after December 17 all programs aimed at Ukraine’s energy independence from Russia will be suspended because instead of introducing the market price for gas they have reinstated the political price along with Ukraine’s rejection of all energy diversification. The modernization of the country has again stopped.
