These points of view would come into conflict because these two sides have fundamentally different views of what is most important.
It is not insulting companies to say this, but they are concerned mostly with making money. This is simply how capitalism works. Companies have a duty to their stockholders to make money. So they want to be able to sell their drugs at the same kinds of high prices that they can get in the West.
By contrast, the NGOs feel that the most important thing is to help the people who have AIDS and to prevent the disease from spreading. They are charitable organizations that are interested in helping people rather than in profit.
In this case, the capitalist point of view comes into conflict with the point of view of charitable organizations that don't care about the companies profits.
