International law addresses piracy through various ways, especially via the United Nations Convention on the Law of the Sea 1982 (hereby referred to as UNCLOS) as well as multiple instruments under the International Maritime Organization (IMO), including treaties, guidelines, codes of conducts or recommendations, etc. These documents provide the definition of piracy and how parties should address this crime. However, such solutions are only to a certain extent because of the interpretation and enforcement issues in international law, especially for an issue that is still evolving in practice like piracy.
