The emergence of the WTO was a complex process, so later access to the same Republic of Croatia was difficult and time-consuming. The World Trade Organization was founded in 1995 as a fundamental organization of trade and legal policy worldwide. As the world economy has become more transit, global, market integrated and free, so much of the impact relates to trade between countries. The main feature of globalization is technological development that enables the spatial and temporal reduction of the world. An integral part of the story is the Republic of Croatia, which became the the 140th member of the World Trade Organization on November 30, 2000. This gives Croatia the opportunity for stronger and more competitive trade influence and economic development. In 1987, the World Commission on Environment and Development first defined sustainable development. And as the definitions changed the essence remained the same. The emphasis of sustainable development is on society, the environment, and the economy. One of the fundamental tasks of the WTO is to respect and promote norms for the protection of the human environment. Prerequisites for achieving the goals are sustainable development and environmental protection, as well as constant and increased care for underdeveloped members. Sustainable development is visible through the membership of the Republic of Croatia, which shows the state of the country and is also one of the tasks of the WTO, as well as Croatia, which as a member state is an integral part of the world's largest organization. Although the goals and tasks of the World Trade Organization are well thought out underdeveloped member states are not overwhelmed by the organization due to many requirements that are difficult to meet and fulfill. The WTO is showing great bias and favoring more developed countries. The COVID 19 pandemic has made trade even more difficult as supply chain disruptions, delivery delays, price hikes and inflation have occurred.
