Changes in trade policies between countries are one of the factors that influence global economic dynamics. This policy covers various regulations, agreements and practices implemented by countries to regulate the flow of goods and services across international borders. Several important aspects in changing trade policies between countries include tariffs, quotas and technical arrangements. One of the main factors that triggers changes in trade policy is the domestic political and economic situation. Countries facing economic challenges, such as trade deficits or financial crises, often implement protectionist policies to protect local industries. For example, high tariffs can help domestic industries compete with cheaper imported products. However, this policy can trigger retaliation from other countries, which often leads to trade wars. Free trade agreements also form the basis for policy changes between countries. Through this agreement, countries commit to reducing trade barriers, such as tariffs and quotas, to increase trade volumes. Examples include the ASEAN Free Trade Area (AFTA) and the North American Free Trade Agreement (NAFTA). In addition, the World Trade Organization (WTO) plays an important role in regulating and facilitating trade negotiations between countries, as well as setting the rules that must be followed. Technological changes and digitalization also have a major impact on trade policy. Electronic trading enables faster and more efficient transactions, and opens up new markets for small and medium businesses. However, this also requires the country to update regulations regarding taxes and personal data protection. Countries that quickly adapt to these changes gain a competitive advantage in global trade. Environmental aspects are also increasingly becoming a concern in trade policy. With increasing awareness of the issue of climate change, countries are starting to implement policies that promote environmentally friendly products. This policy not only supports sustainability but also provides excellence for products that meet global environmental standards. In the context of globalization, changes in trade policies between countries are seen as a necessity to encourage economic growth and improve people’s welfare. However, countries must also be careful not to fall into discriminatory practices that could harm international relations. The effectiveness of trade policy depends heavily on international cooperation and the ability of countries to adapt to global market dynamics.
