A dispute arises when a member government believes another member government is violating an agreement or a commitment that it has made in the WTO. The WTO has one of the most active international dispute settlement mechanisms in the world. Since 1995, 606 disputes have been brought to the WTO and over 350 rulings have been issued. 

When do disputant parties settle a dispute by?

When the disputant parties settle the dispute themselves by discussion or by adjusting the disagreement, the process is called a negotiation. The dictionary meaning of negotiation defines it as a discussion aimed at reaching an agreement. Hence in a case of disagreement, the method of negotiation can be used to reach a state of peaceful agreement.
