When 50 countries gather, a simple "Let's get along" won't do. Each country has tons of problems of their own. Large and mighty countries just quietly stare at each other, and let their proxies bicker... To them, resources and technologies are a weapon. They say that all countries are equal, but that's just lip service. Wealth and poverty and religious differences, won't allow them to be equal... Even if they shake hands, they step on each other's feet with a grin.
