The monograph presents scenarios of situations where foreign investments suffer damage. These model scenarios are based on thorough analysis of real cases, facts from the ground and recent arbitral practice (relating namely to arbitrations against Russia, Syria or Libya). This allows the author, in the next step, to ascertain what rules are applicable to the conduct of states towards foreign investments, but also to demonstrate how they apply in real-case scenarios. In particular, the work identifies and applies to these tailored scenarios relevant norms of international investment law, international humanitarian law and international human rights law. These regimes are relevant for protection of foreign investment, but they differ as to the situations they govern, parties whose conduct they regulate and obligations they stipulate. It is therefore appropriate to analyse in their interconnection how these rules govern typical situations that may arise during armed conflict and what particularly they prescribe. On the basis of application of these rules on the defined scenarios, the monograph focuses on the issue of applicability of investment treaties in occupied territories and on interactions and on the issue of conflict of norms in situations where foreign investments qualify as military objectives.
