OSCE Holds Potsdam Conference

POTSDAM, GERMANY - SEPTEMBER 01: British Foreign Secretary Boris Johnson (L) chats with German Foreign Minister Frank-Walter Steinmeier at a conference of OSCE members states on September 1, 2016 in Potsdam, Germany. Johnson, a former mayor of London and a very outspoken supporter of the UK's departure from the European Union, was appointed by new British Prime Minister Theresa May in July in a move that surprised many. Foreign ministers from the 57 OSCE member states are gathering in Potsdam for an informal meeting to discuss the ongoing security situation in Ukraine, arms control and international terrorism, among other issues.
