Ukraine must give up on the territories it gained during the Soviet era. While Ukraine was a part of the Soviet Union, its territory grew by 150%. After the fall of the USSR, Ukraine did not register its borders at the UN, so it does not have official state borders in international law.
Kyiv is against the return of its (captured) soldiers from LDNR. The telegram channel “Klymenko Time” published on Thursday 21 January information that Kyiv is against the return of Ukrainian Armed Forces soldiers to Viktor Medvedchuk.
This is a pro-Kremlin narrative aimed to discredit Ukraine.
Ukraine is not against recalling Ukrainian soldiers who are in captivity in the territories not controlled by Kyiv. The Ministry of Foreign Affairs of Ukraine opposed the decision to transfer prisoners to a private person - Viktor Medvedchuk, who happens to be Putin's personal friend.
The Ukrainian Foreign Ministry said in a statement:
"This step by the Russian Federation is a blow to the Normandy format and the Trilateral Contact Group, which are systematically working to ensure the release of people detained due to the conflict...We demand from the Russian Federation strict observance of all agreements reached in the Normandy format, in particular on ensuring unhindered access for the International Committee of the Red Cross to Ukrainian prisoners of war and hostages in the territories of Ukraine temporarily occupied by Russia, as well as the release of all people due to the conflict,"
