According to international law, Russia’s territorial claim over Crimea shall not be recognized as it was brought about by a violation of the prohibition of violence. Despite this obligation, several arbitral tribunals have recently accepted jurisdiction in claims brought by Ukrainian investors under the Russia-Ukraine BIT and declared the Russia-Ukraine BIT applicable. I consider the arbitral tribunals’ reasoning to be inconsistent with the duty of non-recognition. Therefore, I analyze possible alternative ways in which Ukrainian and non-Ukrainian investors can obtain protection for their investments in Crimea under the Russia-Ukraine BIT without implicitly recognizing Russia’s territorial claim over Crimea.
