I think you just explained why that wouldn't work. The UN is composed of its member countries. The conferences are held by representatives appointed from those countries. Those representatives will, in most cases, be representing the corporations who got their employer into power. For example, you may have noticed John Bolton, our former ambassador to the UN, is very keen on invading Iran as soon as possible. This works out nicely for companies that sell tanks, cruise missiles, guided bombs, etc. He was nominated into his position by George Bush. The Bush administration had initially planned to attack 7 countries in 5 years, including Iran. When you start to notice all those no-big contracts going to Haliburton, and all the rest of the extreme overexpenditures on this war, it's pretty clear who Bush is loyal to, and Bolton was chosen by Bush, on behalf of those companies. Now, if people like him are running all the UN meetings, they aren't going to be interested in helping the poor, unless they are representing companies who can skim some profit off of that. For the most part, they will only be interested in maintaining the status quo in order to maintain and expand the economic and political power of their respective corporations. The only competition between them will be the corporations in countries who get hit with sanctions because they're cutting into more powerful corporations' markets.
