A notable characteristic of the July 2026 NATO Summit in Ankara was the absence, for the second yr in a row, of the 4 leaders of NATO’s Indo-Pacific associate international locations, collectively referred to as the IP4: Australia, Japan, New Zealand, and South Korea. It could be tempting to see this as proof that NATO-IP4 relations are on the downturn, however a deeper evaluation doesn’t assist such a conclusion.
First, the principle variable affecting the presence of the IP4 leaders was not the curiosity of NATO and IP4 international locations in continued engagement, however the nature of the summits themselves. As well as, it isn’t clear that common leader-level attendance at annual NATO summits continues to be a vital driver of NATO-IP4 relations. The logic for continued cooperation between NATO and the IP4 is as robust as ever within the present geopolitical local weather.
Reasonably than the optics of NATO-IP4 relations, the underlying substance and course of engagement, the subleader degree institutionalization of those relationships, and their software on the sensible degree are the crucial components for gauging dedication.
Summits Match for Objective
The important thing distinction between the summits in 2022, 2023, and 2024 and the summits in 2025 and 2026 is of their construction. All three of these earlier summits concerned two days of North Atlantic Council (NAC) conferences at chief degree. The latter two summits had just one. Getting that attenuated timeline required slicing out the NAC leaders’ conferences with associate international locations.
That change in construction primarily displays the realities of america. To paraphrase the phrases of an allied official, NATO understands that President Donald Trump doesn’t have the curiosity or consideration span for a two-day summit, so the summits needed to be shortened – merely as a matter of practicality and lifelike expectations.
It’s true that the IP4 leaders have been nonetheless invited, and that the majority didn’t attend – that reality is indeniable. This resolution turns into far more comprehensible when examined in context, nonetheless. With out a chance to participate in NAC discussions, the IP4 leaders have been successfully invited to the rehearsal dinner, however to not the marriage itself. From the potential views of busy heads of state, such an invite merely doesn’t carry the load essential to edge out competing home and regional priorities. It’s a pleasant alternative, however – together with the simultaneous attendance of their protection ministers at complementary summit occasions for these friends – not a compelling one.
It will be a mistake, nonetheless, to equate summit illustration with the present well being of the partner-alliance relationships. Chief attendance on the 2022, 2023, and 2024 summits, which every featured a NAC leader-level session with IP4 companions, was crucial to shifting NATO-IP4 relations ahead, establishing their significance publicly, and creating the momentum from the highest essential to activate nationwide bureaucracies. These objectives have now been met considerably, making continued leader-level attendance much less important.
By 2024, all 4 of the associate international locations had signed new Individually Tailor-made Partnership Program (ITPP) paperwork to map out their bilateral NATO relationships. All of them had devoted ambassadors to NATO at embassies in Belgium, and have been engaged in particular NATO-IP4 precedence areas of cooperation: Ukraine, cyber protection, disinformation, and expertise.
Definitely, leader-level consideration is one of the best driver for continued inside momentum inside every nation and for the additional deepening of those relationships. That mentioned, high leaders’ absence from common summit-based intervals might be offset, to a major extent, by the larger involvement of protection and international ministers and the continued visits of high-level NATO officers to the area. There’s a clear effort being made at NATO to create such alternatives and by IP4 companions to reply.
The IP4 ministers of protection (minister of protection trade for Australia) attended the Ankara summit and met with their NATO counterparts at a NAC protection minister-level working dinner and a NATO protection trade discussion board, increasing on protection and international ministerial engagements from latest years. In 2025, new NATO Secretary Basic Mark Rutte traveled to Tokyo to fulfill with Japan’s prime minister and different high-level NATO officers visited the area, persevering with a development from the previous few years. Maybe most significantly, the NATO-IP4 relationships – bilaterally and because the IP4 – are already institutionalized on the ambassador and dealing ranges in Brussels.
Geopolitical Drivers for Continued Engagement
There are a minimum of 4 clear geopolitical drivers for continued engagement between NATO and its Indo-Pacific companions, primarily based on mutual pursuits and profit. These are the existence of associated calls for and expectations from america, the interconnected nature of safety within the Indo-Pacific and Euro-Atlantic theaters and the prospect of multi-theater battle, mutual assist for a rules-based worldwide system, and alternatives for protection industrial cooperation. Along with the NATO-IP4 precedence areas of cooperation agreed on the Washington Summit in 2024 (Ukraine, cyber protection, disinformation, and expertise), and the ITPPs, these drivers create a transparent foundation for additional relations.
As international locations which are all shut U.S. allies (or within the case of New Zealand, a key associate), the IP4 and NATO nations can trade finest practices and views on the now extra fragile U.S. alliance relationship, together with by coordinating messaging and consulting on the right way to preserve america engaged constructively past the Western Hemisphere and inside acknowledged guidelines and norms on using pressure. In different phrases, there’s a clear utility in having associates which are sharing related experiences concerning their ally america, notably because the U.S. president points units of related calls for and expectations for U.S. allies, no matter location. This was evident largely not too long ago in Trump’s requires elevated regional burden-sharing and help with the Israeli-U.S. battle towards Iran.
Mutually shared considerations about multi-theater battle involving China and Russia additionally underscore the necessity to coordinate. Because the battle in Ukraine has made abundantly clear, safety challenges within the Euro-Atlantic theater have important, if oblique, safety penalties for the Indo-Pacific theater and vice versa. The issues of inter-theater deterrence and protection dynamics haven’t gone away as a result of america has shifted its consideration away from Europe. Nor has the worry of coordinated multi-theater conflicts by China and Russia.
Persevering with robust relations between NATO and the IP4 is crucial for pondering by collectively what could be vital to organize for and tackle simultaneous Chinese language or North Korean and Russian led contingencies. The IP4 companions are additionally incorporating classes from the Ukraine battle into their very own safety assessments, with Japan – the place the teachings of Ukraine are anticipated to characteristic prominently within the up to date nationwide safety and protection paperwork anticipated later this yr – as a first-rate instance.
Equally, NATO and the IP4 share a need to assist a rules-based worldwide system or crucial components of it. That is notably true in areas the place the companions can work effectively collectively, corresponding to norm setting, public diplomacy, countering disinformation, coordination of political statements, and assist for Ukraine. For the IP4 international locations, together with many center powers in Europe, safety and prosperity has rested on a predictable, rules-based system. There’s nonetheless an unwillingness to again away from that regardless of Russian, Chinese language, and now U.S. propensities to undermine such a system.
There’s additionally the very sensible difficulty of coordination on protection industrial cooperation. A lot of probably accessible avenues for such coordination between IP4 international locations and NATO allies exist. Joint improvement and co-production of protection applied sciences and gear is one. Right here for instance, NATO is reportedly in talks with the IP4 companions about taking part in its Starlift mission, an alliance community for sharing house satellite tv for pc launch capabilities. Japan can be exploring entry to NATO’s Protection Innovation Accelerator for the North Atlantic (DIANA), targeted on next-generation applied sciences. Japanese participation in DIANA might open new protection export alternatives in European markets now that Tokyo has additional relaxed restrictions on arms exports.
One other avenue is the diversification of defense-related provide chains, particularly away from rivals and towards allies like Australia, Japan, or South Korea. A 3rd is coordinating on munitions manufacturing and stockpiling, provided that the shortfall in munitions has been a key lesson of the wars in Ukraine and now Iran.
A fourth main avenue is larger interoperability by joint acquisition/procurement and the combination of technical requirements throughout gear/munitions. South Korea and NATO are in talks for a joint procurement settlement popping out of the Ankara Summit, for instance. Australia signed an settlement with NATO’s Help and Procurement Group in 2025.
On to Tomorrow
NATO’s curiosity in and engagement with its IP4 companions – and vice versa – continues, if merely much less publicly. That is sensible going ahead, for the close to time period a minimum of. Now that the NATO-IP4 relationships have been established, normalized, and largely institutionalized, the main target ought to transition to sustaining common engagement on necessary areas of mutual curiosity and to deepening by sensible, substantive cooperation.
