This chapter explores the complex and multifaceted nature of agreements on normalisation and statehood, which play a critical role in resolving conflicts and modifying sovereign relations between states. It begins by examining how such agreements aim to create, restore, or maintain normal relations, addressing key issues like sovereignty, territorial integrity, and diplomatic recognition. The chapter categorises these agreements into two main groups: those that facilitate state creation through secession and those that focus on normalising diplomatic relations between existing states. It highlights the importance of these agreements in managing self-determination conflicts, which are often sensitive and intractable. The chapter also delves into the political and legal controversies that arise in such agreements, particularly their use of vague language and the challenges posed by differing legal interpretations. Finally, it examines the involvement of third-party mediators and the complex dynamics of enforcing and sustaining these agreements, given their significant political and legal implications.
