The fruitless U.S.-North Korea summit will have a mixed impact on China, South Korea and Japan, each of which has different strategic interests at stake.

The two-day summit between U.S. President Donald Trump and North Korean leader Kim Jong Un failed to yield any written agreement, sparking concern that denuclearization of the Korean Peninsula will not be realized in the near future.

Foreign affairs experts say that China is not altogether displeased in the outcome, since it is keen to continue playing a pivotal role in East Asia, and that South Korea is disappointed because it will likely face difficulties in deepening economic cooperation with the North amid tight international sanctions on its neighbor.
