The first trilateral talks aimed at ending the war in Ukraine since February are set to take place in Abu Dhabi, with senior officials from Moscow, Kyiv, and Washington participating. According to US officials, both Russia and Ukraine have demonstrated a degree of flexibility in discussions regarding control over Ukraine's eastern regions post-conflict. The talks will focus on addressing security concerns for both countries, with a potential emphasis on establishing a new "security architecture" that could involve measures such as security consultations and de-escalation strategies. However, significant disagreements persist between the two sides, particularly regarding Ukraine's eastern region of Donetsk, which remains occupied by Russia. The US official emphasized that the Donetsk issue would not be resolved without addressing the overall "security architecture" for the region. European leaders have expressed a desire to be involved in the peace talks and receive assurances from both sides regarding their security concerns. The discussions come as US President Donald Trump continues his efforts to broker peace, despite facing skepticism from Ukrainian officials who worry about potential concessions that may not favor Ukraine's interests.
