States powers have a direct impact on most human activities. They have different kinds of power depending on the principles and practical realities of the state. What grew exponentially during the 19th and 20th century are international exchanges such economic, political, social and cultural. Introducing a form of permanent international cooperation would help regulate these exchanges. This was going to be done by the United Nations. To do so, their system included commissions and others relating to all aspects of international cooperation.
States play a key role in the economy by promoting its growth by their politics. States also close or open their borders to international trade which is a great influence. This is done for what is more profitable for the state itself. In the second half of the 20th century, regional economic agreements have tremendously grown. What have also grown are the international transactions since the end of the Second World War. Multinational corporations are exceptionally important to the globalization of the economy. Reason being is because of their responsibility to the major portion of global production and also sell goods and services all around the world. Governments cannot make laws concerning the agricultural methods but can manage the production in their own territories. They can control the quality of products that enter their territory and also adopt international production standards.
Homogenization of culture in several countries has been led by economic globalization and the development of communications technologies. The building of universal peace is being seeked by the United Nations Educational, Scientific and Cultural organization (UNESCO). How this is being worked upon is by advancing the cooperation among nations through education, science, culture and communication.
