Missile Tests, Taiwan, and the Art of Diplomatic Compartmentalisation

By Bernard Yegiora

The Marape-Rosso Government's decision to close the Chinese Taipei Economic and Cultural Office in PNG has attracted considerable attention. Coming only days after Prime Minister James Marape and Foreign Minister Justin Tkatchenko publicly criticised China's recent missile test in the Pacific, some observers may view the decision as contradictory.

It is not.

If anything, it demonstrates an important principle of diplomacy that is often misunderstood: states rarely allow disagreement in one policy area to define an entire bilateral relationship.

Only days earlier, PNG had expressed concern over China's ICBM test in the Pacific. Prime Minister James Marape reiterated his vision of the Pacific as an "Ocean of Peace," while Foreign Minister Justin Tkatchenko questioned the wisdom of conducting missile tests near small Pacific Island states.

Those statements reflected PNG's concerns about regional security.

The decision to close the Taiwanese trade office reflects something entirely different.

It reflects PNG's long-standing commitment to the One China Policy, which has guided relations with the People's Republic of China since diplomatic relations were established in 1976.

Foreign Minister Tkatchenko's statement makes this explicit. The closure is presented as an administrative alignment with National Executive Council Decision No. 144/2026 and as reaffirming PNG's unwavering commitment to the One China Policy. The statement also describes the move as strengthening state-to-state trust and creating opportunities for expanded strategic cooperation, trade and socio-economic development between PNG and China.

This distinction is important.

Too often, international relations are viewed through a simplistic lens of "friends" and "enemies." In reality, diplomacy is considerably more nuanced.

Countries frequently cooperate economically while disagreeing on security matters. Allies regularly experience disputes over trade, defence spending, human rights or environmental policy without abandoning their broader partnerships. Likewise, strategic partners may express concern over particular actions while continuing to pursue deeper economic cooperation.

PNG's recent actions illustrate this reality.

The Government criticised an action—the missile test—but reaffirmed the relationship.

This is neither inconsistency nor weakness.

It is diplomacy.

From a Melanesian perspective, this approach is perhaps unsurprising. Melanesian societies have traditionally valued dialogue, reconciliation and the restoration of relationships after disagreement. Conflict is rarely viewed as permanent. Once concerns have been expressed, attention shifts towards rebuilding trust and maintaining long-term relationships.

This cultural disposition appears to be reflected in PNG's foreign policy.

The Government did not allow disagreement over a regional security issue to undermine nearly five decades of diplomatic relations with China. Instead, it reaffirmed the broader strategic partnership while maintaining its position on the missile test.

That is an example of diplomatic compartmentalisation.

Whether one agrees with the decision to close the Taiwan office is a separate debate. Questions concerning trade, economic engagement and relations with Taiwan deserve careful consideration on their own merits.

However, the timing of the decision provides an important lesson about foreign policy.

Successful diplomacy is not about agreeing with another country on every issue.

Nor is it about reacting emotionally to every disagreement.

It is about managing multiple interests simultaneously.

PNG's relationship with China encompasses trade, investment, infrastructure, education, people-to-people exchanges and regional diplomacy. A disagreement over one security issue does not erase these broader interests.

Equally, maintaining a strong bilateral relationship should not prevent PNG from expressing legitimate concerns when regional security is affected.

This is the balancing act that middle and small powers perform every day.

The challenge for PNG is not choosing between China and Taiwan, or between China and its traditional partners. The challenge is maintaining an independent foreign policy that protects PNG's national interests while preserving constructive relationships with all major partners.

If the recent missile debate demonstrated the importance of strategic realism, and the need for stronger scientific advice within the National Security Agency, then the Taiwan decision demonstrates another equally important lesson.

Foreign policy is rarely about choosing one issue over another.

It is about managing all of them at the same time.
