Treaties are agreements between sovereign states, and occasionally between states and international organizations. Treaties can include conventions, covenants, charters, and statutes, all of which are legally binding under international law. There are two main types of treaties: bilateral and multilateral. Bilateral agreements are concluded by a limited number of states (usually two), and typically address a narrow set of issues that are unique to specific parties and particular circumstances. Multilateral treaties, on the other hand, establish generalized principles of conduct that apply to a wide range of states without regard to the future particularistic interests of the parties or the strategic exigencies that may exist in a particular occurrence. Treaties can serve a wide variety of functions: ending wars and establishing conditions for peace; creating new international organizations or alliances; generating new rules of coexistence and cooperation; regulating a particular type of behavior; distributing resources; and initiating new rights and obligations for future relations. No single organization or agency has the authority to enforce treaty commitment. Rather, treaties can be enforced in at least two ways. First, states can use diplomatic, economic, and/or military coercion. Second, some treaties establish their own enforcement mechanisms; for example Chapter VII of the United Nations Charter grants enforcement authority to the Security Council.

Multilateral diplomacy is the management of international relations by negotiations among three or more states through diplomatic or governmental representatives, but it can also be engaged in by representatives of non-state actors. Multilateral negotiation is characterized by multi-parties, multi-issues, multi-roles, and multi-values. The level of complexity is far greater than in bilateral diplomacy as is the level of skill needed to manage that complexity. It can be based on multilateralism, or have multilateralism as a goal, but it can also be pursued by those who do not. Multilateralism can be defined as global governance of the many, and a major principle is the opposition to bilateral discriminatory arrangements. Classic diplomatic studies focused on bilateral diplomacy. However, the growth of international organizations in the 20th century increased interest in multilateral diplomacy, which has developed since its origins in 1648. Increasing attention has been paid to the role of non-state actors and new forms of diplomacy affected by globalization and the digitization of information. In the 21st century, multilateral diplomacy faces unique challenges and calls for reform of international organizations and global governance.
Foreign policy analysis (FPA) occupies a central place in the study of international relations. FPA has produced a substantial amount of scholarship dealing with subjects from the micro and geographically particular to the macro relationship of foreign policy to globalization. It brings together many different subject areas, indeed disciplines, as between international relations and comparative politics or political theory, or history and political science. FPA generates case studies of major world events, and the information that probes behind the surface of things, to make it more possible to hold politicians accountable. Meanwhile, officials themselves are ever more aware that they need assistance, conceptual and empirical, in making sense of how those in other countries conduct themselves and what can feasibly be achieved at the international level. However, each subject under FPA needs to be revitalized through the development of new lines of enquiry and through the struggle with difficult problems. Work is either already under way or should be pursued in eight important areas. These are (i) foreign policy as a site of agency, (ii) foreign policy and state-building, (iii) foreign policy and the domestic, (iv) foreign policy and identity, (v) foreign policy and multilateralism, (vi) foreign policy and power, (vii) foreign policy and transnationalism, and (viii) foreign policy and ethics.

In contrast with humanitarian access or the provision of humanitarian assistance, humanitarian intervention is commonly defined as the threat or use of force by a state to prevent or end widespread and grave violations of the fundamental human rights of individuals other than its own citizens, without the permission of the state within whose territory force is applied. In support of their cause, advocates of humanitarian intervention often draw upon and reference the authority of the notional “just war.” The four main ways by which humanitarian intervention has been connected to the idea of the just war relate to the ideals of self-determination, punishment, responsibility, and conditional sovereignty. For a humanitarian intervention to be considered legitimate, there must be a just cause for intervention; the use of force must be a last resort; it must meet the standard of proportionality; and there must be a good likelihood that the use of force will contribute to a positive humanitarian outcome. The historical practice of humanitarian intervention can be traced from the nineteenth century to the recognition of the Responsibility to Protect by the World Summit in 2005 and its application in Darfur. Major conceptual debates surrounding humanitarian intervention include the problematic relation between sovereignty and human rights, the legal status of intervention, the issue of multilateralism versus unilateralism, and the quest for criteria for intervention.
