The main focus of the Committee on Trade and Development is to help developing countries through trade. The World Trade Organization (WTO) is often accused of working in favor of the big countries and ignoring the problems of less developed countries. This committee works to try to make sure that the WTO is helping even the less developed countries.
The Committee on Trade and Development does a number of things in pursuit of this goal. One thing it does is to try to develop rules that will work in favor of the less developed countries. As an example of this, the committee got the WTO to approve rules that would allow the vast majority of exports from less developed countries to enter world markets without any quotas or tariffs. Another thing the committee does is to help less developed countries try to solve problems associated with the sizes of their economies. For example, the committee is helping less developed countries to find solutions that will help them deal with the fact that they lack economies of scale in most of their industries.
In these ways and others, the Committee on Trade and development focuses on helping less developed countries to develop through trade.
