刘和平：泽连斯基松口愿撤出顿巴斯？俄乌局势在绝境中迎来希望？

Group 1 - The core viewpoint of the article is that the latest 20-point "peace plan" proposed by Zelensky may not signify a significant breakthrough in Russia-Ukraine negotiations, as both the U.S. and Ukraine have issued statements reflecting a shared stance that lacks consensus on key issues [2][3]. - The real obstacle to negotiations lies in the territorial sovereignty of the four eastern regions of Ukraine, particularly Donbas, which the 20-point plan fails to address adequately, merely listing divergent positions from Russia, the U.S., and Ukraine [3]. - The plan includes at least six points related to Ukraine's security guarantees, indicating Zelensky's heightened sense of insecurity, as he relies on external parties like Russia and the U.S. for security assurances [5]. Group 2 - Zelensky's recent willingness to consider establishing a "free economic zone" in Donetsk represents a potential shift towards U.S. proposals, but it is contingent upon Ukraine first obtaining security guarantees [7][8]. - The ambiguity in Zelensky's statements regarding the extent of the "free economic zone" and the conditions for Russian withdrawal suggests that any perceived concessions may not be substantial [8][9]. - The idea of a "free economic zone" could provide a new approach to resolving the conflict, proposing a demilitarized zone and international oversight for security, which may facilitate future negotiations [12].
