The Bureau International des Expositions (BIE) is an international organization based in Paris, France. It was established in 1928 to oversee and regulate world expos, which are large-scale exhibitions showcasing culture, innovation, and technology. The BIE ensures that these events are organized fairly and that they adhere to specific standards, promoting international cooperation and understanding. World expos, often referred to as expositions universelles, are held every few years in different countries. They provide a platform for nations to present their achievements and ideas, fostering dialogue and collaboration. The BIE plays a crucial role in selecting host cities and supporting the successful execution of these significant global events.
