Globalization refers to the increasing integration of economies around the world through trade and financial flows. It involves companies operating on a global scale to produce and market similar products worldwide. While globalization provides opportunities for growth, it also faces criticisms such as promoting cultural imperialism. Multinational corporations play a major role in driving globalization as they expand operations across borders in search of new markets and efficiencies. However, multinationals also encounter challenges abroad and can negatively impact host countries. Regional trading blocs have formed to reduce trade barriers between member nations, but they also divert trade away from low-cost non-member producers and create both winners and losers among participating economies.
