North Korea declares emergency in border town over suspected Covid-19 case

North Korean leader Kim Jong-un convened an emergency meeting of the ruling Workers' Party and adopted a "maximum emergency system" against the coronavirus pandemic after a defector returned from South Korea with symptoms of the deadly virus.

The North Korean leader declared an emergency and a lockdown in a border town after the suspected person returned from neighbouring South Korea after illegally crossing the border.

If confirmed, it would be the first case officially acknowledged by North Korean authorities.

Kim convened an emergency politburo meeting in response to what he called a "critical situation in which the vicious virus could be said to have entered the country", the North's KCNA state news reported.

A person who defected to South Korea three years ago returned across the fortified border that divides the two Koreas to the town of Kaesong this month with symptoms of COVID-19, the disease caused by the virus, KCNA reported.

"An emergency event happened in Kaesong City where a runaway who went to the south three years ago, a person who is suspected to have been infected with the vicious virus returned on July 19 after illegally crossing the demarcation line," KCNA said.

KCNA did not say if the person had been tested, but said an "uncertain result was made from several medical check-ups of the secretion of that person's upper respiratory organ and blood", prompting officials to quarantine the person and investigate anyone he may have been in contact with.

One analyst said the announcement was important, not only because North Korea was for the first time reporting a suspected coronavirus case but also because it suggested it was appealing for help.

'An ice-breaking moment for N Korea to admit a case'

"It's an ice-breaking moment for North Korea to admit a case," said Choo Jae-woo, a professor at Kyung Hee University.

"It could be reaching out to the world for help. Perhaps for humanitarian assistance."

North Korea is under huge economic pressure because of international sanctions over its nuclear programme.

Cho Han-bum, a senior fellow at the Korea Institute for National Unification in Seoul, said it was significant that North Korea was reporting its first suspected coronavirus case was imported.

"North Korea is in such a dire situation, where they can't even finish building the Pyongyang General Hospital on time. Pointing the blame at an 'imported case' from South Korea, the North can use this as a way to openly accept aid from the South," Cho said.

KCNA did not elaborate on how the "runaway" had crossed one of the world's most heavily guarded borders but said the incident was being investigated and the military unit responsible would face "severe punishment".

Meanwhile, South Korean officials were checking to see if a defector had indeed crossed back into the North this month, the South's Yonhap news agency reported.

In January, North Korea declared the launch of a national emergency system against the new coronavirus, shutting down its borders and tightening quarantine measures, reports Yonhap News Agency.

North Korea has received thousands of coronavirus testing kits from Russia and other countries and imposed strict border closures.

Thousands of people in North Korea were also quarantined as it took precautions to prevent a coronavirus outbreak but restrictions had recently been eased.

North Korea is yet to report a Covid-19 case but has intensified its preventive efforts across the country, calling its fight against the virus is a "political matter" that will determine the fate of the country.
