Pyongyang is allowing the limited access to the site to publicize its promise to halt underground tests and launches of intercontinental ballistic missiles. It unilaterally announced that moratorium ahead of a summit between leader Kim Jong Un and President Donald Trump scheduled for June 12 in Singapore. The eight South Korean journalists were excluded because Pyongyang has cut off high-level contact with Seoul to protest an exercise with the US military. Amid growing concern over the success of the summit, South Korean President Moon Jae-in was to meet with Trump in Washington later Tuesday. The group that arrived by charter flight from Beijing is made up of media from the UK, Russia, China and the United States. The journalists, including an Associated Press Television crew, will stay at a hotel in this port city on North Korea’s east coast before traveling by train to the site, which is in the northeastern part of the country. The dismantling ceremony is expected to be held in the coming days, depending on the weather. The North’s decision to close the Punggye-ri nuclear test site has generally been seen as a welcome gesture by Kim Jong Un to set a positive tone ahead of his summit with Trump. But it is mainly just a gesture. The North has already conducted six underground tests at the site — including its most powerful ever, last September — and Kim told ruling party leaders last month that further testing is unnecessary. North Korea could build a new site if it decides it needs more testing or could dismantle the tunnels into Punggye-ri’s Mount Mantap in a reversible manner. Details of what will actually happen at the site are sparse, but Pyongyang’s apparent plan to show the closure of the site to journalists, not international nuclear inspectors, has been raised as a matter of concern. The North’s decision to exclude the South Korean media, however, was a more troubling sign of discord. The South Koreans were expected to participate in the trip, but were left behind in Beijing after the North refused to grant them visas. The South’s Yonhap news agency reported the North refused to accept a list of the reporters on Monday, making it “technically hard’ for the South Korean media to join the event. The exclusion, a sharp departure from the conciliatory mood between the Koreas since the South hosted the Olympics in February, deepens a standoff that began last week when Pyongyang signaled it would cut off all high-level talks with Seoul in response to the joint military exercises. The North claimed the exercises involved US strategic nuclear assets — including nuclear-capable B-52 bombers — and violated the spirit of detente on the peninsula. Washington denies the bombers were part of the drills. That same day, Pyongyang also warned Kim might “reconsider” the US summit over hardline comments from Trump’s new national security adviser, John Bolton. Bolton suggested the North must denuclearize before it can receive any reciprocal benefits from Washington. Pyongyang insists the precondition for denuclearization is for the US to end its “hostile policy.”
