After the Second World War and the devastated Europe, there were numerous attempts to design an institution that would work to improve the economies of its member states. After the IMF, IBRD, GATT and WTO in 1944, the World Bank and its group were formed, which still works as a development institution. After the war, it helped transition countries and devastated countries to develop, and today it finds its role around the world by offering loans, loans, advice, analysis and knowledge. In addition to financial support in which the two parties participate in contracting, it responds immediately in crisis situations and provides assistance, so in the case of the COVID-19 pandemic in the Republic of Croatia, for example, provided assistance in the event of a major earthquake in Zagreb in 2020. The World Bank offers low interest rates when issuing loans to countries for various projects (sustainable development, public and private sector, education, health, etc.) and the number of repayment years depends on the country's development and the amount of the loan. The projects notified by the countries undergo a detailed and sometimes long-term analysis in order to implement the goal effectively, efficiently and to fulfill its purpose, and the contracting parties were satisfied. The future of the World Bank is in good hands, as its expert team, together with representatives of the members, meets on a daily, monthly and annual basis, and the plans it announces for the next five and ten years deal with various topics; policies, global trade, the problem of climate change, etc.
