Non-discrimination is just of the key principles of the WTO's trading system. Others include :
- transparency ( clear information about policies,rules and regulations )
- increased certainty about trading conditions (commitments to lower trade barriers and to increase other countries' access to one's markets are legally binding)
- simplification and standardization of customs procedure, removal of red tape, centralized databases of information, and other measures to simplify trade, known as "trade facilitation".
Together, they make trading simpler,cutting companies' costs. That, in turn, means more jobs and better goods and services for consumers.
