However, the summit can set the tone for the entire Korean Peninsula. First of all, the DPRK and ROK will enter a new round of active interaction. The Moon Jae-in administration is eager to launch a series of North-South economic cooperation projects, beginning with restarting the Kaesong Industrial Complex and the Mt. Kumgang tourist resort. For Moon, the Hanoi summit is crucial to his own plans for advancing the North-South relationship. The longstanding tension in the peninsula will be greatly reduced, and economic development will become the main theme.
Second, the DPRK has succeeded in achieving diplomatic breakthroughs, greatly improving relations with neighboring countries and major powers, and gradually getting rid of its long-standing isolation. From the first Singapore summit to the upcoming Vietnam summit, relations between the DPRK and Southeast Asian countries will also be restored and developed. The full restoration of diplomatic relations is undoubtedly conducive to the DPRK's economic development.
Finally, with the improvement of U.S.-DPRK relations, the close military and intelligence links between the U.S., ROK and Japan will be gradually weakened. In particular, the current deterioration between the ROK and Japan has been intensified, and the cracks in the sharing of defense costs and trade issues between the U.S. and ROK, the U.S. and Japan have already appeared.
The trilateral is in jeopardy, and Trump's attitude of the alliance is being criticized within his country. If the Vietnam summit re-emerges with the plan to hurt the allies, the gap between the three countries will be more intensified.
The second summit of the U.S. and DPRK will bring another round of cooperation and contest in Northeast Asia in 2019.
