Strategic competition in the Indo-Pacific is increasingly taking place in the “gray zone”—the space between routine state competition and open warfare. Rather than relying solely on conventional military confrontation, states are employing hybrid tactics such as economic coercion, cyber operations, disinformation campaigns, and limited military provocations to gradually shift the strategic balance in their favour.

China, North Korea, and Russia are among the most active practitioners of gray zone strategy. Their activities are deliberately calibrated to remain below the threshold that would trigger a large-scale military response, allowing a to challenge the rules-based order while avoiding outright conflict.

For policymakers and military planners, this presents a difficult dilemma. Traditional deterrence models were designed to prevent major wars, not persistent low-level coercion. As gray-zone competition intensifies across the Indo-Pacific, regional states must consider how to deter and respond to these activities without inadvertently escalating the situation.

Understanding the actors involved, and the tactics they employ, is therefore essential. The following sections outline how China, North Korea, and Russia conduct gray zone campaigns across the Indo-Pacific and how these activities collectively challenge regional stability.

China: Gradual Strategic Expansion

China arguably conducts the most sophisticated and comprehensive gray zone campaign in the Indo-Pacific. Beijing’s approach combines military presence, maritime coercion, economic pressure, and legal strategies to expand its influence while avoiding direct confrontation.

In the maritime domain, China frequently uses coast guard vessels and maritime militia to harass foreign ships in disputed waters, particularly in the South China Sea. These forces operate in ways that blur the line between civilian and military activity, allowing Beijing to apply pressure while maintaining plausible deniability.

China also conducts frequent aircraft incursions and large-scale military exercises near Taiwan, while maintaining persistent patrols around the Senkaku Islands. These operations serve multiple purposes: demonstrating military capability, testing regional responses, and normalizing Chinese presence in contested areas. Moreover, Beijing employs cyber espionage, economic coercion, and diplomatic strategies sometimes described as “lawfare,” often passing domestic laws that extend jurisdiction into contested spaces to codify expansive claims, selectively invoking international law, and using legal ambiguity to its advantage. These efforts allow China to reinforce its territorial claims and political narratives while staying below the threshold of open conflict. Over time, such actions gradually reshape the strategic environment in China’s favour.

North Korea: Coercion Through Provocation

North Korea relies heavily on gray zone tactics to pressure its opponents while avoiding the disastrous consequences of full-scale war on the Korean Peninsula.

Cyber operations are one of Pyongyang’s most important tools. Groups such as the Lazarus Group have conducted large-scale hacking campaigns targeting financial institutions, governments, and cryptocurrency exchanges. These cyber activities not only generate revenue for the regime but also demonstrate North Korea’s growing technological capabilities.

In addition to cyber operations, North Korea regularly conducts missile launches, artillery exchanges near disputed maritime boundaries, and military demonstrations aimed at raising tensions in the region. These examples are limited military provocations designed to signal resolve without triggering open conflict.

North Korea also operates extensive sanctions-evasion networks. Through covert maritime trade, smuggling operations, and cyber-enabled financial crime, the regime generates revenue while circumventing international restrictions. These activities allow Pyongyang to sustain its economy and military programs despite heavy sanctions pressure.

Taken together, North Korea’s gray zone strategy enables the regime to coerce its adversaries, generate financial resources, and maintain strategic relevance without crossing the threshold of major war.

Russia: Information Warfare and Strategic Signalling

Although Russia’s primary strategic focus lies in Europe, Moscow also conducts gray zone activities in the Indo-Pacific that challenge regional stability and Western influence.

Cyber operations remain a central element of Russia’s approach. Moscow-linked actors have been associated with intrusions targeting government systems and critical infrastructure in countries such as Japan and Australia. These operations are often accompanied by online disinformation campaigns aimed at undermining public trust and influencing domestic political debates.

Russia also engages in strategic military signalling across the region. Long-range bomber patrols and naval deployments near areas such as the Sea of Japan and the East China Sea demonstrate Russia’s military reach and reinforce its presence in the Indo-Pacific. In some cases, these activities occur alongside Chinese forces, highlighting increasing coordination between Moscow and Beijing. Such cooperation amplifies the strategic message that Russia and China are capable of jointly contesting Western and allied presence in the region.

Russia also maintains sanctions-evasion networks that facilitate illicit maritime trade, including ship-to-ship transfers involving North Korea. These networks allow Moscow to sustain economic ties while bypassing international restrictions.

The Strategic Challenge of Gray Zone Competition

Gray-zone campaigns pose a growing strategic challenge for Indo-Pacific states. Because these activities remain below the threshold of armed conflict, they are difficult to deter using traditional military tools. Yet over time, they can gradually erode regional stability and shift the balance of power. This raises an important question for policymakers: how should states respond to persistent gray zone coercion without escalating into major conflict?

One approach is to use limited, proportionate conventional responses to push back against gray-zone activities. However, such responses must be carefully calibrated to prevent unintended escalation. This is where broader strategic deterrence may play an important role.

A stronger Indo-Pacific security framework—potentially including deeper military integration among regional allies and partners—could provide the stability needed to manage escalation risks. In particular, a future Indo-Pacific nuclear security architecture could serve as a strategic backstop. As much as nuclear deterrence underpins NATO’s conventional defence posture in Europe, a similar framework in the Indo-Pacific could help ensure that responses to gray zone provocations remain limited rather than spiralling into major war.

Preparing for Persistent Competition

Gray zone competition is likely to remain a defining feature of Indo-Pacific security in the coming decades. China, North Korea, and Russia are already using these tactics to challenge the existing strategic order while avoiding direct confrontation.

For regional states, the challenge is not simply responding to individual incidents. It is developing a deterrence framework capable of managing persistent, low-level coercion across multiple domains. Without such a framework, gray zone activities will continue to stress the limits of allied resolve and gradually reshape the strategic landscape. Strengthening regional cooperation, improving resilience against hybrid tactics, and reinforcing strategic deterrence will therefore be essential steps in preserving stability in the Indo-Pacific.

The digital Silk Road (DSR), China’s initiative to invest in critical telecommunications and emerging technology in foreign countries, is a vehicle to lower the barriers to cyber coercion and propagate the digital curtain. By embedding its “model of technology-enabled authoritarianism” in recipient nations, Beijing seeks to shape the digital ecosystems of other countries in ways that serve its strategic interests. Such attempts call for a proactive and coordinated response from the United States and its regional partners—one that builds a resilient, tech-driven organization capable of countering China’s digital expansion across the the Indo-Pacific.

The United States and China are engaged in a great power competition, one which has seeped into multiple theaters and domains. The Indo-Pacific region is generally understood to be the frontline of this contest.

However, China’s burgeoning technological capacity has led to cyberspace being a critical juncture in this competition; one where traditional borders fade, thereby allowing the proliferation of gray zone tactics. Such tactics are deployed in various ways—infiltrating critical infrastructure, cyber espionage, and disinformation campaigns—on key democracies in the region.

Considering the geopolitical significance of the Indo-Pacific, China’s attempts to use cyber coercion to cleave the region from the United States’ sphere of influence highlights a calculated strategy by the Chinese Communist Party (CCP). The region is home to over 50 percent of the world’s population, and 80 percent of global trade volume transits through its channels. It houses “seven of the world’s largest militaries, and five American treaty allies.”

Moreover, digital connectivity and internet adoption rates are the fastest growing compared to any region in the word, making it rife with opportunities and threats. These vulnerabilities not only indicate further volatility for regional governments but could also undermine American national security.

The list of cyber incidents already attributed to Chinese state-sponsored entities is extensive, and its targets are equally expansive. Advanced persistent threat (APT)—long-term, sophisticated, and entrenched cyber intrusions designed to hack, steal, and/or neutralize systems—have been a weapon of choice for those entities. For instance, APT-30 and APT-40, which targeted Association of South East Asian Nations (ASEAN) members and New Zealand’s government, respectively, are reportedly linked to the Chinese government.

Furthermore, American intelligence and cybersecurity agencies recently confirmed that Volt Typhoon, a Chinese state-sponsored entity, compromised American critical infrastructure ranging from telecommunications to water systems; its reach even included US territories such as Guam.

While the specter of ATPs and digital intrusions have entered the purview of several governments in the Indo-Pacific region, individual efforts to deter those threats are futile. This is often due to strategic inertia, a shortage of specialized workers, and asymmetric capabilities.

A consolidated effort by the United States and its regional partners is needed to build consensus, direct resources, and establish a digital enforcement body. This could address those issues while mitigating any potential upheaval from China’s tactics. Fortunately, the groundwork for such a partnership is already in place.

On July 1, 2025, the 10th Quad foreign ministers’ meeting was hosted by US Secretary of State Marco Rubio, where he was joined by his counterparts from Japan, India, and Australia. It was the second such meeting since January, signifying the importance placed on the vision of the group by the Trump administration.

The measures agreed upon as a result are further evidence to that fact—initiatives to bolster maritime and transnational security, economic security, critical and emerging technology, among others. Therefore, the vast security mandates of those initiatives provide a viable path to constructing a techno-centric partnership while addressing the region’s strategic, skills, and capabilities gaps when it comes to deterring China’s digital incursions.

The decision to expand the Indo-Pacific Partnership for Maritime Domain Awareness (IPMDA)—a technology-focused initiative to augment the maritime security landscape—provides a practical foundation for a techno-centric partnership. Its stated goal of developing a “common operating picture” for the IPMDA could lead to the basis for a strategic consensus among potential members.

Furthermore, incorporating insights from the first Maritime Initiative for Training in the Indo-Pacific (MAITRI) workshop could assist in closing the skills gap for a regional digital workforce, further adding to the partnership’s feasibility.

Additional features which could be utilized for the partnership and address the capabilities gap include the Quad Cyber Challenge and the Quad Partnership on Cable Connectivity and Resilience. The Cyber Challenge seeks to enhance the cyber ecosystem, digital awareness, and resourcing among member nations.

The Partnership on Cable Connectivity and Resilience, on the other hand, bears a more tactical responsibility of strengthening telecommunications infrastructure, specifically, undersea cables—arguably the most critical component of the digital ecosystem. Although these initiatives are focused on Quad member-nations, they could be expanded in a larger forum to engage ASEAN and Pacific subregional organizations such as the Pacific Island Forum, providing more opportunities for resource allocation.

There is institutional and strategic momentum behind the formation of a tech-centric partnership, not to mention the critical security imperative that exists. The broad consensus, coupled with the runway to take near-term action, makes this a prospective enterprise. Such concrete action is necessitated if the US and its regional allies expect to maintain a free and open Indo-Pacific and establish an active deterrent to China, which seeks to write the rules and draw the margins of the evolving digital age.
