We are writing to express our concern about the government of Croatia’s obstruction of the work of the International Criminal Tribunal for the Former Yugoslavia (ICTY). Consistent with previous European Union (E.U.) demands, we hope that the E.U. will put the issue of cooperation high on its bilateral agenda with Croatia and specifically insist upon the surrender of indictees to the ICTY as a condition of further development of the relationship under the Stabilization and Association Agreement.
