Abstract
This chapter discusses the application of international humanitarian law (IHL) to EU military operations outside of the European Union (EU). It describes where the Union has performed best: promoting the development, acceptance, and respect of IHL by others. EU restrictive measures may be taken in its commercial policy, its foreign and security policy, and its development cooperation policy. A field in which the European Union may have a direct impact on violations of IHL is the export of arms. EU member states continue to be involved in armed conflicts, but EU law did not govern their involvement. Therefore, the relationship between IHL and EU law is fortunately not (yet) an issue of daily concern for practitioners and EU institutions. In the instances in which the European Union has been a military actor abroad, IHL arguably did not apply because the Union had not become a party to an armed conflict.
