WASHINGTON, (Reuters) – The United States imposed new sanctions Wednesday on Milorad Dodik of Bosnia, the Bosnian Serb leadership. Dodik aims to expel the Serb Republic from Bosnia’s armed forces. They also accused him of corruption, and threatening Bosnia and Herzegovina’s stability and territorial integrity.

In a statement, the U.S. Treasury Department stated that it had also placed sanctions against Alternativna Televizija D.o.o. Banja Luka accuses Dodik of purchasing it in order to advance his agenda and exercise personal control.

These are the first uses of an executive Order issued June 1. They enable the United States and other countries to identify those who could threaten stability or peace in the Western Balkans.

Bosnia has been in its worst political crisis since 1991, when the Bosnian Serbs prevented the government from working. Serb lawmakers also voted for the independence of the Serb Republic to be expelled from the state institutions.

“Milorad Dodik’s destabilizing corrupt activities and attempts to dismantle the Dayton Peace Accords, motivated by his own self-interest, threaten the stability of Bosnia and Herzegovina and the entire region,” Brian Nelson, Treasury’s under secretary for terrorism and financial intelligence, said in the statement.

Three-and-a half years of ethnic war in Bosnia ended in 1995 with the U.S.-brokered Dayton Peace Agreement. Around 100,000 were killed and two million people were forced to flee their homes.
