- ASEAN is an organization established in 1967 comprising 10 Southeast Asian countries that promotes regional diplomacy, education and professional exchange, environmental collaboration, and free trade. - Regional diplomacy benefits countries more than bilateral diplomacy as it allows for third party mediation to prevent conflicts from escalating and brings together more countries for larger scale problem solving. - International diplomacy consisting of too many countries like the UN makes it difficult to reach common solutions as there are many differing opinions and it is inefficient in addressing issues.
