of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) in Yushchenko in relation to his severe poisoning. The 2004 TCDD levels in Yushchenko's blood serum were 50,000-fold greater than those in the general population. This new study also concluded that the dioxin "was so pure that it was definitely made in a laboratory". On 27 September 2009, Yushchenko said in an interview aired on Channel 1+1 that the testimony of three men who were at a dinner in 2004 at which he believes he was poisoned is crucial to finishing the investigation, and he claimed these men were in Russia.

Satsyuk returned to Ukraine in 2012 and tried to relaunch his political career, but didn't succeed.

During 2005, Yushchenko was in confident mood, making such pledges as solving the Gongadze case to the removal of Russia's Black Sea Fleet. In August 2005, Yushchenko joined with Georgian President Mikheil Saakashvili in signing the Borjomi Declaration, which called for the creation of an institution of international cooperation, the Community of Democratic Choice, to bring together the democracies and incipient democracies in the region around the Baltic, Black, and Caspian Seas. The first meeting of presidents and leaders to discuss the CDC took place on 1–2 December 2005 in Kyiv.
