This article deals with two of the strongest conclusions from general studies on the causes as well as absence of interstate war：the importance of territorial disputes and the significance of regime type. The first is termed the “territorial peace” hypothesis；the second is known in the literature as the “democratic peace” proposition. This article discusses if these two issues have to be settled prior to the building of quality peace between states that have a history of war among them. These findings are used to analyze the actual Western European experience since World War II and then relating this to the East Asian situation today. In this way this article also points to important differences. Still，the territorial issues take on particular role if the East Asian region is to move towards more durable and positive conditions，what might constitute ingredients of quality peace. At that moment，also Real politik concerns enter the equation.
