NATO needs to send a signal that it will contain "Russian imperialism" and every move to aid Ukraine will help it do this, Czech Foreign Minister Jan Lipavsky said on May 29, as the military alliance meets this week to discuss support for Kyiv. Foreign ministers of NATO's 32 members will gather in the Czech capital Prague on May 30-31 to hammer out agreements for later when NATO leaders meet in Washington in July, focusing on putting support for Ukraine on a more stable long-term footing.
