Kim Yo-jong, the younger sister of the North Korean government, has shot a statement by South Korea's foreign minister questioning the province administered by Kim Jong-un, recording zero COVID-19 cases since the beginning of the year.
A minister named Kang Kyung-wha last week said a clean case record in North Korea has been impossible since the outbreak last year.
Unexpectedly, the allegation angered Kim, describing Kang's comment as a reckless accusation that exacerbated the murky Seoul-Pyongyang relationship.
Worse, Kim, who is synonymous with being the second ruler after her brother made threats, said, "We will not forget his allegations and he will probably suffer the consequences."
Experts also admit it is impossible for the province to be free from coronavirus infection even though authorities have tightened borders and blocked international flights by the end of January.
The COVID-19 pandemic has made North Korea more "North Korea", more closed and more detailed on every action taken to prevent the epidemic by closing the Chinese-Russian border, including deporting diplomatic forces.
The year 2020 is not so lucky for North Korea because the region is facing various crises to the point of inviting Kim Jong-un when he was hit by a natural disaster.
South Korea-North Korea relations were also tested with an office explosion in Kaesong and the issue of shooting and burning South Korean officials to the point of forcing Jong-un to apologize publicly.
