UN Security Council resolutions ban North Korea from testing ballistic missiles and if the launch is confirmed it would represent a new challenge to President Joe Biden’s efforts to engage with Pyongyang.
The missile launches highlight the threat North Korea’s illicit weapons programme poses to its neighbours and the international community, the United States military’s Indo-Pacific Command said in a statement on Thursday.
The command said it was monitoring the situation and consulting with allies.
Japan lodged a formal protest through its embassy in China and said the test threatened peace and safety in the region, while South Korea’s National Security Council expressed deep concern.
The Japanese government said one missile flew about 450 km (280 miles) and landed outside the Japanese exclusive economic zone, indicating it was a short-range missile.
“The first launch in just less than a year represents a threat to peace and stability in Japan and the region and violates UN resolutions,” Japanese Prime Minister Yoshihide Suga said in comments aired by public broadcaster NHK.
Suga said he would ensure a safe and secure Olympics and “thoroughly discuss” North Korea issues including the launches with Biden during his visit to Washington next month.
South Korea’s Joint Chiefs of Staff earlier reported at least two “unidentified projectiles” were fired into the sea between the Korean peninsula and Japan from North Korea’s South Hamgyong Province on the east coast.
South Korean and U.S. intelligence agencies were analysing the data of the launch for additional information, the JCS said in a statement.
South Korea’s presidential Blue House will convene an emergency meeting of the national security council to discuss the launches.
Japan’s coast guard warned ships against coming close to any fallen objects and asked them to provide information to the coast guard.
North Korea has not tested a nuclear weapon or its longest-range intercontinental ballistic missiles (ICBMs) since 2017, ahead of an historic meeting between leader Kim Jong Un and former US President Donald Trump in 2018.
US officials confirmed North Korea carried out a new projectile launch, without offering details on the number or kind of projectile detected.
There was no official comment from the White House or State Department.
The Biden administration is in the “final stages” of reviewing its North Korea policy, senior US officials told Reuters this week.
Analysts have noted a change in wording from the previous administration, emphasising the “denuclearisation of North Korea”, rather than the whole peninsula – a more unilateral position likely to be anathema to Pyongyang.
“North Korea’s military activities after reaffirming ties with Beijing raise questions about how China is complicit in sanctions evasion and may be enabling the Kim regime’s threats to the region. This will increase calls in the US and elsewhere to sanction Chinese firms involved in illicit trade,” he said.
Over the weekend North Korea fired two short-range cruise missiles, US and South Korean officials said, but Biden played down those tests as “business as usual” and officials in Washington said they were still open to dialogue with Pyongyang.
Even short-range ballistic missile tests would be a “step-up” from the weekend test, and allow North Korea to improve its technology and send a proportionate response to recent US-South Korea military drills, said Vipin Narang, a nuclear affairs expert at the Massachusetts Institute of Technology in the United States.
The test launches should not torpedo diplomatic efforts, but they are a reminder of the cost of the failure to secure a deal with Pyongyang, he said.
Biden’s diplomatic overtures to North Korea have gone unanswered, and Pyongyang said it would not engage until Washington dropped hostile policies, including carrying out military drills with South Korea.
North Korea has continued to develop its nuclear and missile programmes throughout 2020 in violation of UN sanctions dating back to 2006, helping fund them with about $300 million stolen through cyber hacks, according to independent UN sanctions monitors.
In early 2018, North Korea announced a moratorium on testing nuclear weapons and ICBMs, though it says it no longer feels bound by that after negotiations with the Trump administration faltered.
