When news broke out that a North Korean man was murdered at Kuala Lumpur International Airport 2 (KLIA2), the public was intrigued as to the motives behind the attack.

Even after it was confirmed by Malaysian authorities that the man was indeed Kim Jong-nam, the estranged half-brother of North Korean leader Kim Jong-un, foreign relations analysts believed that the incident would have little, if any effect on the country’s diplomatic ties with North Korea.

Since then, however, the North Korean envoy to Malaysia and Wisma Putra have been trading barbs over the matter.
