Everything I've mentioned can be traced back to the Industrial Revolution and the market economies that have been generated from it. Essentially, industrial nations need to change the way business is done with other nations with less economic prowess. Sure, money is typically the focus, but it is important for that mentality to be complimented by thought for the well-being of other nations. Now, that is a difficult task to accomplish to say the least, but it starts by freeing nations of current massive debt (not necessarily all debt, but a sufficient percentage) so that they are not forced into trade "partnerships" that benefit one immensly, and the other slightly.
Suppose all countries did what China did in the early days of its economic boom. Open up countries to massive foreign investment at a good return to investors. This would promote exploration of under-utilized and undeserved markets. It would create a global community that allowed for the further understanding of countries the world over.
Bottom line, a way is needed to ensure countries that are suffering get an infusion of resources to become sustainable primarily on their own. A massive expansion of basic agricultural practices, engineering technologies, medical care, advanced education, and basic infracture to help developing nations get onto the path to significantly improve their quality of life.
To do this, cooperation from the international community is required, and I am not talking about the UN. What the UN does is good, but ineffective because they are so heavily funded by few nations that carry major weight in decisions of the UN's future. Countries need to meet independently to take action and address the serious problems facing these countries.
I believe the underlying issue of all concerns is poverty, however, poverty stems from unequal access to resources. So those with access to resources either need to share, but since it appears like these countries are unwilling to share without something in return, it is the developing nation and industrialized nations responsibilities to find a way for the developing nation to obtain its own resources and make them last.
