North Korea has carried out a “very important” test at its Sohae satellite launch site, a rocket testing ground US officials once said Pyongyang had promised to close, state media KCNA have reported.

The reported test comes as a year-end deadline North Korea has imposed on resuming missile tests nears, warning it could take a “new path” amid stalled denuclearisation talks with the US. The KCNA report called it a “successful test of great significance” on Saturday but did not specify what was tested.

South Korea’s defence ministry said South Korea and the US were cooperating closely in monitoring activities at major North Korean sites including Tongchang-ri, the area where Sohae is located.

Missile experts said it appeared likely the North Koreans had conducted a static test of a rocket engine, rather than a missile launch, which are usually quickly detected by neighbouring South Korea and Japan.

“If it is indeed a static engine test for a new solid or liquid fuel missile, it is yet another loud signal that the door for diplomacy is quickly slamming, if it isn’t already,” said Dr Vipin Narang, a nuclear affairs expert at the Massachusetts Institute of Technology.

“This could be a very credible signal of what might await the world after the New Year.”

Tensions have risen ahead of the deadline set by North Korea, which has called on the US to change its policy of insisting on Pyongyang’s unilateral denuclearisation and demanded relief from punishing sanctions.

On Saturday, North Korea’s ambassador to the United Nations said denuclearisation was off the negotiating table with the US and lengthy talks with Washington were not needed.

“The results of the recent important test will have an important effect on changing the strategic position of the DPRK once again in the near future,” KCNA reported, using the initials of North Korea’s official name, the Democratic People’s Republic of Korea.



The test is the latest in a string of statements and actions from North Korea designed to underscore the seriousness of its deadline.

North Korea has announced it would convene a rare gathering of top ruling-party officials later this month, and on Wednesday state media showed photographs of the North Korean leader, Kim Jong-un, taking a second symbolic horse ride on the country’s sacred Mount Paektu. Such meetings and propaganda blitzes often precede major announcements from North Korean authorities.

While Pyongyang has not specified what its “new path” could be, observers have suggested the launch of a space satellite is a possibility, allowing North Korea to demonstrate and test its rocket capabilities without resorting to overt military provocation such as an intercontinental ballistic missile (ICBM) launch.

“Such testing is meant to improve military capabilities and to shore up domestic pride and legitimacy,” Leif-Eric Easley, a professor at Ewha Woman’s University in Seoul, said of Saturday’s test.

“North Korea is avoiding violations of its long-range missile test moratorium for now, but it is still improving the propulsion and precision of its missiles so that it can claim a credible nuclear deterrent.”

Kim Dong-yub, a former South Korean navy officer who teaches at Kyungnam University in Seoul, said North Korea may have tested a solid-fuel rocket engine, which could allow North Korea to field ICBMs that are easier to hide and faster to deploy.

“North Korea has already entered the ‘new path’ that they talked about,” he said.



President Donald Trump told reporters in June 2018 after his first summit with Kim that North Korea had pledged to dismantle one of its missile installations, which US officials later identified as Sohae.

Shortly after that summit, analysts said satellite imagery showed some key facilities at Sohae being dismantled. However, after the second summit this year, which ended with no agreement, new imagery indicated the North Koreans were rebuilding the site.

At the time, Trump said he would be be very disappointed if the reports of rebuilding were true.

“Remember this is at the site that was supposedly dismantled as a ‘denuclearisation step’,” Narang said. “So this is a first step at ‘renuclearising.’ Reversible steps are being … reversed.”

In recent weeks, media reports indicated a high number of US military surveillance flights over the Korean peninsula, suggesting growing expectation of North Korean tests.

Commercial satellite imagery captured on Thursday by Planet Labs showed fresh activity at the Sohae satellite launching station and the presence of a large shipping container, CNN reported, with analysts suggesting it indicated a test was imminent.
