US President Donald Trump has reaffirmed the principle of "complete denuclearisation of North Korea," a stance which will shape the US administration's policy on the Korean Peninsula for the foreseeable future. This marks the first time since his inauguration that the administration has explicitly included the phrase in an official diplomatic document, offering clarity on its approach, as reported by The Korea Times. 

The importance of North Korea's full denuclearisation was discussed during a meeting between Trump and Japanese Prime Minister Shigeru Ishiba over the past weekend, which highlighted Trump's reaffirmation.

To encourage a coordinated approach to North Korea negotiations, the US and Japan will further utilise their trilateral partnership with South Korea.

While South Korea is primarily concerned about North Korea's potential to add a nuclear capability to its arsenal, Japan remains committed to bringing back scores of missing Japanese citizens believed abducted by the North in the last decades of the 20th Century. At least one, perhaps more are understood to be alive in North Korea but even the repatriation of remains of deceased abductees is something Japanese relatives are hoping for.

The declaration was made at the right moment, as worries about a change in US policy grew after Trump's comment that North Korea was a "nuclear power." Discussions on whether the administration would emphasise intercontinental ballistic missiles or nuclear arms control had been triggered by this.

South Korea's government was quick to express its support for the renewed commitment, emphasising that the positions taken by both the US and Japan align with Seoul's long-standing North Korea policy. With its proactive stance, South Korea has worked closely with Washington and Tokyo in the past to maintain a united front in dealing with North Korean provocations.

Meanwhile, North Korea’s leader Kim Jong-un has responded cautiously to Trump’s reaffirmation. Speaking during the 77th anniversary of North Korea's military, Kim criticised US policies for exacerbating global geopolitical tensions. However, in a notable shift, Kim refrained from directly targeting Trump or South Korea, choosing instead to leave the door open for potential future negotiations with the US. His comments about supporting Russia’s military in the ongoing Ukraine conflict indicated his continuing alignment with Moscow, though they lacked the provocative edge that often characterised his rhetoric.

This unusual restraint by Kim suggests a calculated decision to avoid further escalation, choosing to avoid direct confrontation with the Trump administration while keeping avenues open for diplomacy. As the geopolitical landscape evolves, both sides appear to be maintaining their respective positions while ensuring that the prospect of dialogue remains viable.
