European Union nations agreed on Friday to open membership talks with Ukraine next week, officially launching the process for the war-torn country to eventually join the world's biggest trading bloc. At a meeting in Brussels, ambassadors from the 27 EU nations decided to officially open negotiations with Ukraine as well as with Moldova, which Russia has also tried to drag back into its orbit, on Monday in Luxembourg. Ukraine sees EU membership as an important "security guarantee" for a stable future once war with Russia ends.
