Globalisation refers to the growing unification of the world’s economic order through the removal of barriers to international trade such as tariffs, export fees and import quotas. It describes the process by which regional economies, societies and cultures have become integrated through communication, transportation and trade so that they increasingly act and think similarly. Global sourcing is an example of globalisation, accelerating the development of some national economies and changing the mix of economic activities in many countries. See also Offshoring and Sourcing.
