According to Kushner, as a result of the negotiations in Abu Dhabi, it was possible to achieve "an important humanitarian breakthrough: Ukraine and Russia agreed in principle to conduct the largest exchange of prisoners during the war." Also, in announcing a visit to Moscow with Witkoff, Kushner said that they intend to negotiate with Putin on the participation of the Europeans in the negotiations. If he approves their participation, the parties will be able to "achieve much more progress", believes the American president's son-in-law. According to the aide of the Russian president, Yuri Ushkov, the Europeans in the negotiations in Abu Dhabi "worked behind the scenes" with the Ukrainian and American sides. The Kremlin previously reported that the Russian delegation had no contacts with the Europeans at the negotiations in Abu Dhabi.
