Ukrainian and European officials will hold talks in London on Wednesday, according to the Washington Post, and several sources said the United States would offer to recognize Crimea as Russian territory as part of a peace deal and freeze the front lines of the conflict,. Ukraine's allies want to win security guarantees and reconstruction projects for Ukraine in exchange for any such territorial concessions. Among the proposals the United States made to Ukraine in Paris last week was for Washington to formally recognize occupied Crimea as Russian territory and eventually lift sanctions on Russia under a future deal, according to three people familiar with the matter. In exchange, Russia would end hostilities in Ukraine, at a time when the Russian military is gaining momentum on the battlefield and has a considerable advantage in force and weaponry. The Zelensky adviser said Kiev agreed to only part of the U.S. proposal. One western official said the nature of the pressure on Ukraine was "shocking".
