"Russia does not take diplomatic initiatives on Ukraine seriously.", said Ned Price spokesman for the US State Department, APA reports citing Ria Novosti.
According to him, Kyiv has long been taking a serious approach to resolving disagreements with Moscow.
Price said that the lack of progress in this direction is primarily due to the position of the Russian side.
State Department spokesman also said the United States supports a diplomatic process aimed at ending violence and war through dialogue and diplomacy.
