Peaceful settlements of disputes: UN Charter --- When it's about peaceful settlement of disputes among states, the Charter of the United Nations enlists in its Article 33: negotiation, enquiry, mediation, conciliation, arbitration, judicial settlement, resort to regional agencies or arrangments, or other peaceful means of their own choice.

The list is not very different from what is recommended to individuals: it is just that implementing such means is more difficult.
