Examining Australian, British, Japanese, and South 

Korean perspectives

Project Report


The European Leadership Network (ELN) is an 

independent, non-partisan, pan-European NGO 

with a network of nearly 200 past, present, and 

future European leaders working to provide practical 

real-world solutions to political and security challenges.


The Asia-Pacific Leadership Network for Nuclear 

Non-Proliferation and Disarmament (APLN) is a network 

of former and currently serving political, diplomatic, 

and military leaders, as well as senior government 

officials, scholars, and opinion leaders across the 

Asia-Pacific region.

Strategic risks in the Asia-Pacific: Examining Australian, British, Japanese, and South Korean perspectives 2


Executive summary


The deteriorating global security environment, including 

in the Asia-Pacific region, risks undermining the existing nuclear 

order. Regional policy-making is shaped by heightened threat 

perceptions due to factors such as North Korea’s aggressive 

nuclear and military activities, China’s assertiveness in the 

region, and a worsening strategic competition between 

the United States and China.


In an increasingly volatile regional environment, the governments 

of Australia, Japan, and South Korea are making strategic choices 

to address the risks that these developments pose to their 

national security. Meanwhile, the UK is working to strengthen 

its engagement in the Asia-Pacific. Understanding how actors 

in the Asia-Pacific perceive and react to evolving strategic risks 

is important to promote regional and global stability and reduce 

negative impact on the non-proliferation regime.


In the framework of a joint APLN-ELN project funded by the UK 

Foreign, Commonwealth and Development Office (FCDO), experts 

and officials from Australia, Japan, South Korea, and the UK 

identified strategic risks emanating from a shared set of concerns, 

notably North Korea’s nuclear posture and China’s assertive 

behaviour, as well as twin concerns over a potential US retreat from 

the region and the risk of entrapment in a conflict of somebody 

else’s choosing. Yet, there was disagreement on the relative 

immediacy and significance of these threats as well as on their 

impact on the global nuclear order.


All four states view North Korea’s aggressive nuclear posture 

as a “strategic” risk, though they disagree on its degree of immediacy. 

South Korea perceives potential North Korean military aggression 

as the most direct threat, as does Japan, which would be a likely 

target for a North Korean nuclear strike in such a conflict scenario. 

The UK is, for geographical reasons, less concerned about 

any direct threat from North Korea than about the impact of 

Pyongyang’s policies on nuclear risks in the region more broadly. 

Australia is assured that the US presence in the region suffices 

to manage the threat posed by North Korea’s nuclear arsenal, 

which it ranks below concerns over China’s military expansion 

and assertiveness in the region.


In contrast to the perception of North Korea as a relatively narrow 

nuclear threat, the findings of this project suggest that Australia, 

Japan, South Korea, and the UK see much broader “strategic” 

risks emerging from China’s assertive foreign policy, which is 

backed up by its economic clout and expanding nuclear arsenal. 

Australia and Japan are most concerned about the direct threat 

posed to their sovereignty by Chinese behaviour, particularly around 

Taiwan, and the risk of being dragged into an armed conflict with 

China. By contrast, South Korea and the UK are more apprehensive 

of the wider disruptive effects of a confrontation involving China 

on regional stability, based on economic as well as security and 

proliferation concerns.


In light of the perceived strategic risks stemming from China 

and North Korea, the three Asia-Pacific states seek to balance 

their desire for US assurance against their fear of entrapment. 

Mirroring these sentiments, most British participants 

considered the US presence in the region a stabilising 


(Strategic risks in the Asia-Pacific: Examining Australian, British, Japanese, and South Korean perspectives 3)


factor, but some also warned against forcing regional states 

to choose sides.


While the war in Ukraine is perceived as a direct strategic risk by the UK, it serves as an additional prism through which Australia, Japan, and South Korea assess their security environment. However, they disagree on its implications for the region. Some are concerned 

that North Korea and China might seek to replicate the way in which Russia has used nuclear threats to shield its war of aggression 

against Ukraine, while others believe that the war has demonstrated 

the costs of aggression. Consequently, there is also no consensus 

on whether the Russian invasion of Ukraine has made a Chinese 

invasion of Taiwan more or less likely.


British, Japanese, and Australian participants were apprehensive 

of both regional proliferation and broader stresses on the 

non-proliferation regime. South Korean analysts appeared 

comparatively less concerned. Throughout the project, many raised 

concerns over the viability of the Non-Proliferation Treaty (NPT). 

The Chinese nuclear modernisation was perceived as undermining 

the NPT, but potential South Korean proliferation and a subsequent 

domino effect on Japan were also mentioned as a potential 

risk. The Australia-UK-US (AUKUS) security pact was not viewed 

as a proliferation concern by any of the four countries, but some 

analysts acknowledged that it had become a divisive issue that 

could undermine international unity on non-proliferation issues.

Policy recommendations


• Australia, Japan, South Korea, and the UK should coordinate 

their efforts in groups such as the G20, the G7, and the P5 

to call for high-level US and Chinese commitments to an 

official Track 1 dialogue. Australia, Japan, South Korea, and 

the UK should also encourage engagement with China on 

the value of crisis communication channels and seek the 

resumption of military-to-military crisis communication channels 

between the United States and China or set up their own bilateral 

or multilateral channels with China.


• Within the NPT framework, Australia, Japan, South Korea, 

and the UK should encourage the launch of a new working 

group (or groups) as part of the current review cycle to develop 

targeted risk reduction measures, including through discussions 

on risk escalation scenarios and by exploring synergies between 

existing risk reduction initiatives.


• The UK, supported by Australia, Japan, and South Korea, 

should engage China on disarmament verification by sharing 

their experience from participating in verification initiatives 

and by facilitating the development of cooperative disarmament 

verification initiatives for the region.


• To address South Korea’s primary security concern – the risk 

of direct aggression from North Korea – the UK and Australia 

should provide additional support to Seoul on the basis 

of a clearly articulated condition that it does not take any 

concrete steps towards acquiring its own nuclear weapons. 

Such aid could take the form of continued low-key military

cooperation with South Korea. 

The UK, in particular, could also take a greater role in working with South Korea on technological developments, and intelligence and cyber-security issues.


• Australia, Japan, and the UK should use existing diplomatic 

channels to communicate the economic, political, and security 

implications of nuclear armament to South Korea. In particular, 

they should make clear that any move towards nuclear weapons 

acquisition or development will be met with tough sanctions, 

especially against the South Korean nuclear industry.


• The South Korean and Japanese administrations should build 

on the current positive momentum to solidify a bilateral 

framework that includes regular exchanges at both senior 

and working levels.


• As Japan shares South Korea’s concern over North Korean 

aggression, while also being apprehensive of South Korean calls 

for nuclear armament, both countries should consider developing 

exchanges on potential scenarios and responses to a North Korean 

attack. Eventually this could enable Japan to agree to provide 

some form of aid to South Korea in the case of North Korean 

aggression – on the strict condition that Seoul does not take 

any steps towards nuclear armament.
