Options WFP – these are the main directions of its impact on the social environment, defined by its social purpose. In their external features, they are divided into two groups: a socio-political and legal functions. The first group, which is based in the consolidation of the existing system of international relations include:
* Function of maintaining a system of international relations to be stable order;
* Function is counter to the existence and emergence of new relations and institutions that are contrary to its purposes and principles (prevention of conflicts, the prohibition of the threat and use of force, etc.);
* Function of internationalization, in broadening and deepening the relationship between states and thereby strengthening the international community;
* Awareness-raising function, whose meaning lies in the transfer of experience of rational behavior in the Enlightenment on the possibilities of law, education to respect the law and protected their interests and values (especially true for  relatively States, recently embarked on path of integration into the global community).
The second group of functions of WFP, the essence of which is the legal regulation of international relations, consisted of:
* Coordinating function, since the rules WFP establish mutually acceptable standards of conduct in various areas of relations between states;
* Regulatory function, which is manifested in the adoption by States firmly established rules, which are indispensable for their co-existence and dialogue;
* Security functions, the content of which is that the WFP has a rule to encourage States to follow certain rules of conduct;
* Protective feature is the presence of WFP in the mechanisms that protect the legitimate rights and interests of the States (it is not so there exists a supranational enforcement mechanisms, as appropriate states themselves collectively to ensure the maintenance of international right).
An essential quality of WFP is legally binding force. When creating rules WFP as a result of the agreement, there are two main aspects of lawmaking: the first – on the contents of the actual rules, the second – to give it binding force (often by agreeing on the content standards, the state agreed to give it not legal, and political forces that have does not entail international legal character. The agreement states attached binding, and all of WFP as a whole, which is reflected in the principle of good faith of obligations under international law (the principle of pacta sunt servanda – treaties must be respected).
