The EU is also an example of economic union. Economic unions are created when two or more countries agree to allow the free movement not only of goods and services, but also of factors of production such as capital and labour. The participating nations also share a common monetary, social and fiscal policy. In cooperation with partners such as the WTO and the OECD, the World Bank Group informs and supports client countries wishing to sign or deepen regional trade agreements. Concretely, the work of the WbG understands that the world would have almost obtained more free trade from the next round, the so-called Doha round of trade. .
