Internet reports that on March 21 local time, Ukraine President Zelensky said at a joint press conference that Ukraine's top priority is to cease fire and is cooperating with Britain, France and the United States to advance this matter. He emphasized that it is urgent to reach a ceasefire agreement, and monitoring the implementation of the agreement is equally critical. Currently, Uzbekistan is conducting in-depth discussions with Britain, France and the United States on this issue. Zelensky also said that based on past experience, lack of supervision makes it difficult for Russia to maintain the ceasefire. He believes that NATO intervention is the most effective way to ensure Ukraine's security.
