U.S. Secretary of State Hillary Clinton will make a short trip to Europe next week, attending a security conference in Germany before visiting Bulgaria to discuss joint work in Afghanistan, the State Department said Friday. She will participate in the annual Munich Security Conference on February 3-5, which “brings together global leaders to discuss common security challenges,” spokeswoman Victoria Nuland told reporters. Hillary Clinton also will use the occasion to hold “bilateral meetings with a number of her European and other counterparts from around the world,” Victoria Nuland said without providing details of the conference agenda. On February 5, Hillary Clinton will travel to Sofia, Bulgaria to meet with senior Bulgarian officials to discuss joint support for Afghanistan, issues relating to North Africa and the Middle East, energy security, and bilateral cooperation in international law enforcement, the spokeswoman said.
