A
country's
foreign policy, also called
foreign relations policy, consists of self-interest strategies chosen by the state to safeguard its national interests and to achieve goals within its
international relations milieu. The approaches are strategically employed to interact with other countries. The study of such strategies is called
foreign policy analysis. In recent times, due to the deepening level of globalization and transnational activities, the states will also have to interact with
non-state actors. The aforementioned interaction is evaluated and monitored in attempts to maximize benefits of multilateral international cooperation. Since the
national interests are paramount, foreign policies are designed by the government through high-level decision making processes. National interests accomplishment can occur as a result of peaceful cooperation with other nations, or through exploitation. Usually, creating foreign policy is the job of the
head of government and the
foreign minister (or equivalent). In some countries the
legislature also has considerable effects. Foreign policies of countries have varying rates of change and scopes of intent, which can be affected by factors that change the perceived national interests or even affect the stability of the country itself. The foreign policy of one country can have profund and lasting impact on many other countries and on the course of international relations as a whole, such as the
Monroe Doctrine conflicting with the
mercantilist policies of 19th century European countries and the goals of independence of newly formed
Central American and
South American countries.
