North Korean leader Kim Jong Un has ordered at least two people executed, banned fishing at sea and locked down the capital, Pyongyang, as part of frantic efforts to guard against coronavirus and its economic damage, South Korea’s spy agency told politicians.

Mr Kim’s government also ordered diplomats overseas to refrain from any acts that could provoke the United States because it is worried about President-elect Joe Biden’s expected new approach toward North Korea, politicians told reporters after attending a private briefing by the National Intelligence Service.

One of the politicians, Ha Tae-keung, quoted the NIS as saying Mr Kim is displaying “excessive anger” and taking “irrational measures” over the pandemic and its economic impact.

Mr Ha said the NIS told politicians that North Korea executed a high-profile money changer in Pyongyang last month after holding the person responsible for a falling exchange rate.

He quoted the NIS as saying that North Korea also executed a key official in August for violating government regulations restricting goods brought from abroad.

The two people were not identified by name.

North Korea has also banned fishing and salt production at sea to prevent seawater from being infected with the virus, the NIS told politicians.

There are few ways to independently confirm the reported fishing ban and other information given by the NIS to the lawmakers. Mr Ha didn’t say whether the ban applied to all North Korean waters or whether it was still in effect.

North Korea recently placed Pyongyang and northern Jagang province under lockdown over virus concerns.

Earlier this month, it imposed lockdown measures in other areas where officials found unauthorised goods and foreign currencies that were brought in, Mr Ha cited the NIS as saying.

North Korea also made an unsuccessful hacking attempt on at least one South Korean pharmaceutical company that was trying to develop a coronavirus vaccine, the NIS said.

The agency has a mixed record in confirming developments in North Korea, one of the world’s most secretive nations.

The NIS said it could not immediately confirm the politicians’ accounts.

North Korea has maintained that it has not found a single coronavirus case on its soil, a claim disputed by outside experts, although it says it is making all-out efforts to prevent the virus’s spread.

A major outbreak could have dire consequences because the North’s health care system remains crippled and suffers from a chronic lack of medical supplies.

The pandemic forced North Korea to seal its border with China, its biggest trading partner and aid benefactor, in January.

The closure, along with a series of natural disasters over the summer, dealt a heavy blow to the North’s economy, which has been under punishing US-led sanctions.

North Korea’s trade with China in the first 10 months of this year totalled 530 million US dollars, about 25% of the corresponding figure last year.

The price of sugar and seasoning has shot up four times, Mr Ha quoted the NIS as saying.

North Korea monitoring groups in Seoul said the North Korean won-to-dollar exchange rate has recently fallen significantly because people found few places to use foreign currency after smuggling was largely cut off following the closure of the China border.

According to the NIS briefing, North Korea ordered overseas diplomatic missions not to provoke the United States, warning their ambassadors of consequences if their comments or acts related to the US cause any trouble in ties with Washington.

North Korea’s government has remained silent over Mr Biden’s election victory over President Donald Trump, with whom Mr Kim held three summits in 2018-19 over the North’s nuclear arsenal.

While the diplomacy eventually stalled, the meetings helped Mr Kim and Mr Trump build up personal ties and stop the crude insults and threats of destruction they had previously exchanged.

Politician Kim Byung-kee cited the NIS as saying that North Korea is displaying anxiety as its friendly ties with Mr Trump become useless and it has to start from scratch in dealing with the incoming Biden administration.

Experts have been debating whether North Korea will resume major missile tests soon to try to get Mr Biden’s attention.

During past government changes in the US, North Korea often conducted big weapons launches in an attempt to increase its leverage in negotiations with a new US administration.

The NIS expects North Korea will hold a military parade ahead of a ruling party congress in January in a show of force timed with Mr Biden’s inauguration.

North Korea is also likely to use the Workers’ Party congress to lay out its basic policies toward the US, Kim Byung-kee cited the NIS as saying.

Kim Jong Un has said the congress, the first of its kind in four years, will set new state objectives for the next five years.

In a highly unusual admission of its policy failure in August, the Workers’ Party said North Korea’s economy had not improved due to severe internal and external barriers and that its previous developmental goals had been seriously delayed.
