As reported earlier, the United States and Ukraine are actively negotiating a new package of military assistance, which will take into account the specifics of hostilities in eastern and southern Ukraine.
Earlier, Zelenskyy called the EU for full Russia oil embargo and urged to impose sanctions on all russian banks in the next package. Ukraine asked for clear deadlines by when each EU state will either refuse or significantly limit the consumption of gas and oil from russia.
