The World Trade Organisation (WTO) plays a crucial role in promoting international trade and investment. Before the WTO, international trade faced limitations. The WTO was established to create a global institution for trade. It has helped to liberalise trade and investment worldwide. However, disagreements between developed and developing countries have slowed down trade negotiations. Some regional economic organisations have conflicting policies with the WTO, which could weaken its impact. To remain effective, the WTO must ensure fair trade for all member states, especially developing countries.
