Pyongyang : Officials in South Korea and China and sources familiar with US intelligence have cast doubt on media reports that claimed Kim was gravely ill after a cardiovascular procedure, while the White House said it was closely monitoring the issue.

US President Donald Trump, who held unprecedented summits with Kim in 2018 and 2019 in an attempt to persuade him to give up his nuclear weapons, said the South Korean and US reports had not been confirmed and he did not put much credence in them.

“I just hope he’s doing fine,” Trump told a White House news conference on Tuesday. “I’ve had a very good relationship with Kim Jong Un. And I’d like to see him do well. We’ll see how he does. We don’t know if the reports are true.”

Speculation about Kim’s health first arose due to his absence from the anniversary of the birthday of North Korea’s founding father and Kim’s grandfather, Kim Il Sung, on April 15.

But South Korea’s presidential office said Kim appeared to be handling state affairs as usual and that it had no information about rumours regarding his health. Many will now be watching closely for any signs of trouble in North Korea and whether it will address the reports – something it has not yet done.

Mulberry picking, no Kim

On Wednesday, the main headlines from the official Korean Central News Agency (KCNA) included pieces on sports equipment, mulberry picking and a meeting in Bangladesh to study North Korea’s “juche” or self-reliance ideology. The official Rodong Sinmun newspaper carried articles on a self-sufficient economy and anti-coronavirus measures.

There was no mention of Kim’s whereabouts.

Daily NK, a Seoul-based website, reported late on Monday that Kim, who is believed to be about 36, was hospitalised on April 12, hours before the cardiovascular procedure.

It said his health had deteriorated since August due to heavy smoking, obesity and overwork.

Citing one unnamed North Korean source it said Kim was now receiving treatment at a villa in the Mount Myohyang resort north of the capital Pyongyang.

On Tuesday, media broadcaster CNN reported an unnamed US official saying that Washington was “monitoring intelligence” that Kim was in “grave danger” after surgery.

However, two South Korean government officials rejected the CNN claims. China, North Korea’s only main ally, also dismissed the reports.

South Korea’s presidential Blue House said Kim is believed to be staying at an unspecified location outside of Pyongyang, North Korea’s capital, with some close confidants. It said Kim appeared to be normally engaged with state affairs and there has not been any unusual movement or emergency reaction from North Korea’s governing party, military or cabinet.

According to KCNA, Kim presided over a meeting on April 11, discussing coronavirus prevention and electing his sister as an alternate member of the political bureau of the ruling Workers’ Party. State media have since reported he sent greetings to Syrian President Bashar al-Assad and Cuban President Miguel Díaz-Canel as well as arranging special birthday meals for two North Korean officials and a new centenarian.

Kim’s absence from state media often triggers speculation.
