The representatives of Russia and Ukraine will discuss the monitoring of the ceasefire and territorial issues. Bloomberg. In Abu Dhabi, Russian and Ukrainian representatives will discuss territorial issues and proposals to monitor a ceasefire as part of a new round of talks aimed at ending the war, a senior US official said. The official, who briefed reporters on the condition of anonymity, said daily talks are underway with Russia and Ukraine ahead of the trilateral summit, and expressed cautious optimism that both sides could make progress during the two-day talks in Abu Dhabi. The US official said the first meeting would focus on monitoring ceasefires and post-war security, including security consultation mechanisms, crisis communications and de-escalation measures. The second session will deal with territorial issues. The official noted that both sides have shown flexibility in recent days, but did not provide details. According to this official, the American delegation asked Russia to agree that the United States and Europe would provide Ukraine with security guarantees similar to those stipulated in Articles 4 and 5 of the NATO Treaty. A US official expressed doubt about the existing security arrangements, saying the negotiations would have to create a new structure, without specifying exactly what it might include.
