G7 leaders, including President Obama, will meet in Brussels on Wednesday, with the situation in Ukraine and relations with the Putin administration expected to dominate the conversation. A G8 meeting was scheduled to take place in Sochi but was canceled in March following Russia’s annexation of Crimea. The same issues will be discussed elsewhere in the city at a meeting of the NATO defense ministers. In a clear sign of support for Ukraine, President Obama will attend a ceremony in Poland on Tuesday to honor a pro-Kiev Crimean leader. He is also expected to meet Ukraine’s newly elected president.
