North and South Korea have diplomatic and military issues between the two.

"High-level military talks between North and South Korea have broken down after the two sides failed to make progress on a long-running border dispute: the chief North Korean delegate said his side walked out of the talks after concluding that they were "fruitless”. North Korea wants the sea border to the west of the Korean Peninsula to be redrawn further south. The area lies in rich fishing grounds and has been the scene of bloody naval clashes in the past.

Turmoil between countries can lead to many problems, such as war and a disintegration of economic cooperation. These hurt both economies and increase risk factors to any companies, which rely on Korea for business."
