North Korea abruptly stopped importing COVID-19 prevention and control products from China in May, trade data released by Beijing showed, after the country bought face masks and ventilators from its neighbor in previous months.

Daily new cases of fever in North Korea, as reported by its state news agency, KCNA, have been declining since the reclusive country first acknowledged in mid-May that it was fighting a COVID-19 outbreak. However, how many of those cases tested positive for the coronavirus has yet to be revealed.

North Korea did not import any face masks, thermometers, rubber gloves, ventilators or vaccines from China in May, according to data released by Chinese customs on Monday.

That is compared with imports of more than 10.6 million masks, nearly 95,000 thermometers and 1,000 non-invasive ventilators from China in January-April.

South Korea and the United States have offered to provide help, including vaccines, but Pyongyang has not responded.

As Pyongyang has never directly confirmed how many people have tested positive for the virus, the World Health Organization said in June that it assumed the situation was getting worse, not better.

Overall, China's exports to North Korea slumped 85.2% to $14.51 million in May from $98.1 million in April.
