Global strategy refers to a company's approach to expanding its business beyond its domestic market, seeking opportunities in foreign markets. The benefits of a global strategy include economies of scale, improved brand recognition, customer satisfaction, diversification of the business, recovery of R&D costs, emergence of new markets, and reduced global poverty. However, there are also limitations to consider, such as lack of concentration on local demand, cultural influences making market entry difficult, operational risks, dependence on foreign nations, and trade barriers in some places.
