Name three nations in the DPRK's vicinity who are threatened by the DPRK.

The correct answers are: South Korea, Japan and Taiwan.

Explanation:

Although North and South Korea are trying to pursue more peaceful relationships, there still are some tensions remain between the two countries. The tensions between these countries are caused by their different political orientations, but also because these two countries are officially still at war. The Korean War is a civil war that broke out on June 25, 1950, when the Communist Democratic People's Republic of Korea invaded the capitalist Republic of Korea. This conflict was extended when the U. S. and the People's Republic of China entered the war over Cold War Tensions.

The last peace negotiations between these two countries were in 2015. Relations between the two countries have deteriorated since Seoul suspended a joint economic project in North Korea after launching a rocket and testing North. The incident caused North Korea to cut off communications with Seoul, including the termination of its military phone line.

Relations between North Korea and Japan are marked by hostility and tension. The relations between the two countries have been strained since Japan colonized Korea even before the country was divided. After World War II and the division of Korea, numerous problems and disagreements between the two countries continued, from Japan's attitude towards the U. S. to the abduction of Japanese citizens in North Korea.

Taiwan does not recognize North Korea as a state. Although these two countries had some important trade relations in the past, Premier Lai Ching-te approved a total ban on trade between these countries in 2017 because Taiwanese businessmen were accused of selling Taiwanese goods to North Korea and vice-versa.
