Key Security Developments

• Joint Naval Exercises with Russia ("Joint Sea-2026")
  On July 5, 2026, China's Ministry of National Defense announced the commencement of the "Joint Sea-2026" naval exercise with Russia in waters and airspace near Qingdao, East China's Shandong Province. The exercises, which began on July 6 and are expected to run until July 13, involve a guided-missile cruiser, frigate, submarine, and rescue ship from Russia, alongside Chinese guided-missile destroyers, frigates, supply ships, rescue vessels, and submarines. The drills focus on joint response to maritime security threats, including reconnaissance, air and missile defense, and maritime strike operations, followed by joint maritime patrols in the Pacific Ocean. This exercise highlights the deepening military cooperation between China and Russia, aimed at addressing security challenges and promoting regional peace and stability, and is part of their annual cooperation plan.

• Nuclear-Capable Missile Test in the South Pacific
  On July 7, 2026, China conducted a nuclear-capable missile test in the South Pacific, a region designated as a South Pacific Nuclear Free Zone. Reports on July 6 and 10 indicated that a Chinese Navy nuclear submarine launched a missile carrying a dummy warhead, which splashed down into international waters between Tuvalu and the Gilbert Islands of Kiribati. This action was widely criticized by Australia, New Zealand, Japan, and the US as irresponsible, opaque, and undermining regional nuclear norms. The test is seen as part of China's efforts to expand its nuclear arsenal and enhance its second-strike capability, potentially demonstrating its ability to strike the United States with a submarine-launched ballistic missile (SLBM) from its internal waters.

• Increased Chinese Maritime Activity Around Taiwan
  Throughout the week, Taiwan reported significant Chinese military and coast guard activity in the Taiwan Strait and waters east of Taiwan. On July 5, Taiwan tracked seven Chinese naval vessels and seven official ships around the island. On July 6, Taiwan's National Security Chief warned of increasing Chinese maritime activity, with China's Coast Guard announcing massive law enforcement patrols in waters off Taiwan's east. By July 10, Taiwan's Defense Ministry reported 10 PLA aircraft and vessels operating in the Taiwan Strait. These "grey-zone tactics" are seen as a continuous assertion of sovereignty and a demonstration of capability, aiming to establish a "new normal" of Chinese presence in these waters.

• Cybersecurity Threats from China-Aligned Actors
  Persistent cyber threats linked to Chinese government-linked cyber actors, such as Volt Typhoon and Salt Typhoon, continue to target U.S. government, private sector, and critical infrastructure networks. A suspected China-aligned threat cluster, UNK_MassTraction, was observed exploiting critical security flaws (e.g., CVE-2024-42009) in Roundcube webmail software of U.S. and Canadian universities' physics and engineering departments in May and July 2026. Another Chinese threat actor, UAT-7810, is actively refining its custom malware (LONGLEASH) to expand its Operational Relay Box (ORB) network by exploiting vulnerabilities in internet-facing networking devices, including Ruckus wireless routers and ASUS AiCloud Routers. These activities aim to siphon credentials, establish persistent access, and potentially disrupt critical functions.

• China's Expanded Anti-Sanctions Toolkit
  On July 10, 2026, Al Jazeera reported that China is expanding its measures to counter foreign sanctions and export controls, raising risks for multinational companies. Since March, Beijing has passed two new regulations that enhance its ability to retaliate against foreign entities deemed to have threatened its supply chain security or enforced sanctions with "improper extraterritorial jurisdiction." A third draft law would allow Chinese prosecutors to bring cases against foreign organizations and individuals whose "unlawful acts harm the country's national interests or social public interest." This move is part of a broader effort to strengthen China's public interest litigation law and protect its economic interests amidst ongoing trade tensions with the US and EU.

• EU-China Trade Tensions and October Deadline
  EU-China relations remain strained over significant trade imbalances. On July 4, 2026, European Commission President Ursula von der Leyen issued a warning that the EU would retaliate if China does not address the trade imbalance by an October 2026 deadline. This follows an agreement in late June for three months of talks to avoid a trade war over the bloc's €360bn annual import/export imbalance. New customs rules eliminating preferential treatment for low-value imports, significantly affecting Chinese cross-border e-commerce exporters, came into effect on July 1, 2026. China's Foreign Ministry Spokesperson Mao Ning, on July 6, 2026, responded to concerns about "overcapacity" by stating that quality Chinese products find a ready market and that China-EU trade is driven by market demand.

• Commemoration of South China Sea Arbitration Ruling
  On July 10 and 12, 2026, the Philippines, along with the US, Japan, and 11 other countries, commemorated the 10th anniversary of the 2016 Permanent Court of Arbitration ruling that invalidated China's expansive claims in the South China Sea. The joint statement reaffirmed the ruling as "final, legally binding, and definitive" and reiterated strong opposition to destabilizing or unilateral actions, including the use of coast guard, military, and maritime militia forces to harass or obstruct lawful operations. China continues to reject the ruling, and territorial confrontations, particularly between Chinese and Philippine forces, have become more prevalent.

• China-Namibia Strategic Partnership
  From July 5 to 11, 2026, Namibian President Dr. Netumbo Nandi-Ndaitwah paid a state visit to China, where discussions focused on deepening political mutual trust and strengthening cooperation. A joint statement on July 10, 2026, announced the building of a China-Namibia community with a shared future, emphasizing intensified exchanges in peace and security, including personnel training, defense industry, and joint exercises. Namibia appreciated China's Global Security Initiative (GSI) and other proposals, recognizing them as significant for addressing global challenges.

• Amendments to China's Cybersecurity Law
  Effective January 1, 2026, amendments to China's Cybersecurity Law significantly strengthened penalties and expanded the scope of "extraterritorial application." The law now covers all activities that "endanger the security of China's cyber networks," even on foreign-flagged vessels, with potential sanctions such as asset freezes for deemed threats. It also mandates certification for network products and services and strengthens personal information protection, with stricter enforcement for data leaving the country.

• PLA Modernization Goals and "Intelligentised" Warfare
  Chinese President Xi Jinping, on July 1, 2026, urged the military to accelerate its modernization to world-class standards by 2027, focusing on mechanization, informationization, and "intelligentisation." This includes an emphasis on artificial intelligence (AI), unmanned and autonomous systems, and networked information infrastructure. The goal is to develop the capacity to force the unification of Taiwan in the face of U.S. intervention and to become a preeminent military force capable of fighting and winning wars globally by 2049.

Geopolitical Impact and Regional Dynamics

China's security developments from July 05 to July 12, 2026, have significant geopolitical implications, primarily reinforcing a trend of increased assertiveness and strategic alignment. The "Joint Sea-2026" naval exercise with Russia near Qingdao and subsequent joint patrols in the Pacific Ocean signal a deepening comprehensive strategic partnership between Beijing and Moscow. This collaboration, framed as a response to security challenges, is likely perceived by the US and its allies as a direct counter to their influence in the Indo-Pacific, potentially leading to further militarization and heightened tensions in the region. It demonstrates a united front against what both nations view as Western-led containment efforts, impacting regional power balances and potentially encouraging other states to align with either bloc.

The nuclear-capable missile test in the South Pacific on July 7, 2026, is a clear demonstration of China's expanding military capabilities and its intent to project power further into the Pacific. This action, occurring in a designated nuclear-free zone, has drawn strong condemnation from regional powers like Australia, New Zealand, and Japan, as well as the United States. It challenges existing nuclear non-proliferation norms and raises concerns about a potential arms race, particularly in the context of China's stated goal of enhancing its nuclear second-strike capability. This move could push Pacific island nations to strengthen security ties with Western powers, further complicating the strategic landscape and intensifying the competition for influence in a critical maritime domain.

In the Taiwan Strait, the sustained increase in Chinese Coast Guard patrols and military aircraft and vessel activity continues to be a major flashpoint. These "grey-zone tactics" are designed to assert Beijing's sovereignty claims and normalize its presence around Taiwan, gradually eroding the status quo without initiating direct conflict. This persistent pressure keeps Taiwan on high alert and necessitates continuous monitoring and response from its armed forces. The situation in the Taiwan Strait remains a critical indicator of broader US-China relations, with the US reaffirming its commitment to Taiwan's defense, while Beijing views reunification as an "unshakable" commitment. The ongoing tensions underscore the fragility of regional stability and the potential for miscalculation.

Diplomatic and trade relations with major powers remain complex. While the US and China held a summit in May 2026, aiming for "constructive strategic stability," significant differences persist on issues like Taiwan, Russia, cyber-espionage, and trade. The EU's ultimatum to China regarding trade imbalances by October 2026 highlights the growing economic friction, with new EU customs rules impacting Chinese e-commerce. China's expansion of its anti-sanctions toolkit signals its readiness to retaliate against foreign punitive measures, further complicating the operating environment for multinational companies. These developments indicate a global environment where China is increasingly willing to assert its interests, both militarily and economically, leading to a more competitive and potentially confrontational international order.

Military and Defense Analysis

China's military and defense posture during this period reflects a clear and accelerated drive towards modernization and enhanced power projection capabilities. President Xi Jinping's directive on July 1, 2026, to speed up military modernization to world-class standards by 2027, underscores the urgency of achieving a military capable of "intelligentised" warfare. This involves a significant focus on artificial intelligence (AI), unmanned and autonomous systems, and networked information infrastructure, as outlined in the 15th Five-Year Plan. The People's Liberation Army (PLA) aims to develop the capacity to force the unification of Taiwan in the face of US intervention and to become the world's strongest military by 2049, capable of global deployment.

The "Joint Sea-2026" naval exercise with Russia near Qingdao, which commenced on July 5, 2026, is a tangible demonstration of China's evolving force posture and capability development. The participation of guided-missile destroyers, frigates, submarines, and rescue vessels from both sides, engaging in joint reconnaissance, air and missile defense, and maritime strike operations, highlights a growing interoperability and strategic coordination between the two navies. This exercise, followed by joint maritime patrols in the Pacific Ocean, extends China's operational reach and signals its intent to operate more extensively in distant waters, challenging traditional maritime security paradigms in the Indo-Pacific.

The nuclear-capable missile test in the South Pacific on July 7, 2026, is a critical indicator of China's advancements in strategic deterrence. The launch of a submarine-launched ballistic missile (SLBM) from a nuclear-powered submarine, even with a dummy warhead, demonstrates a significant leap in its second-strike capability. This test, likely involving a JL-3 missile with a reported range of 10,000 kilometers, allows the PLA Navy's Type 09IV SSBNs to threaten the US mainland from PRC internal waters, enhancing the credibility of its nuclear triad. This development contributes to China's overall defense spending trends, which saw a 7% increase in the 2026 defense budget, reflecting a sustained investment in advanced military technologies and platforms. The continuous presence of Chinese military aircraft and vessels in the Taiwan Strait also underscores a persistent "grey-zone" strategy aimed at asserting sovereignty and maintaining pressure on Taiwan.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, China is expected to continue its assertive military and diplomatic activities, particularly in the Indo-Pacific. The conclusion of the "Joint Sea-2026" naval exercise with Russia will likely be followed by further statements emphasizing the strengthening of their strategic partnership, potentially leading to more frequent or complex joint drills. We can anticipate continued "grey-zone" operations in the Taiwan Strait and South China Sea, with Chinese Coast Guard and naval vessels maintaining a high presence to assert sovereignty claims. The 10th anniversary of the South China Sea arbitration ruling will likely see continued diplomatic exchanges and counter-narratives from China, rejecting the ruling while other nations reaffirm its validity. On the economic front, the October 2026 deadline set by the EU for addressing trade imbalances will be a critical period, potentially leading to new retaliatory measures from either side if negotiations fail. Cybersecurity threats from China-aligned actors are also expected to persist and evolve, targeting critical infrastructure and sensitive research institutions in Western nations.

Critical flashpoints and risk areas: The Taiwan Strait remains the most critical flashpoint. Any perceived escalation of US or allied support for Taiwan, or a significant increase in Taiwan's defensive capabilities, could trigger a more forceful response from Beijing, potentially leading to a miscalculation or accidental confrontation. The South China Sea is another high-risk area, especially around disputed features where Chinese and Philippine vessels frequently interact. The recent nuclear-capable missile test in the South Pacific also raises the stakes, increasing the potential for misinterpretation of military intentions and challenging regional stability. Cyber warfare represents a constant, pervasive threat, with the potential for significant disruption to critical infrastructure globally, and the new amendments to China's Cybersecurity Law could lead to increased legal friction for foreign entities operating within or interacting with China's cyber domain. Trade disputes with the EU and US could also escalate, impacting global supply chains and potentially leading to broader economic decoupling efforts.

Indicators to monitor: Key indicators to monitor include the frequency, scale, and location of PLA military exercises, particularly those involving joint operations with Russia or those near Taiwan and in the South China Sea. Any further nuclear or long-range missile tests by China would signal continued strategic expansion. Developments in China's defense industry and technology sector, especially regarding AI and unmanned systems, will be crucial for assessing its military modernization trajectory. On the diplomatic front, the outcomes of EU-China trade talks and any new retaliatory measures from either side will be important. The nature and frequency of cyberattacks attributed to China-aligned groups will also indicate the intensity of cyber espionage and potential sabotage efforts. Finally, statements and actions from the US and its allies regarding their Indo-Pacific strategies and responses to Chinese assertiveness will shape Beijing's future actions.

Strategic recommendations: For nations concerned about China's security posture, a multi-faceted approach is recommended. This includes strengthening regional alliances and partnerships to present a united front against coercive actions, particularly in the South China Sea and Taiwan Strait. Enhancing maritime domain awareness and intelligence sharing in disputed areas is crucial to deter grey-zone tactics and prevent escalation. Investing in cybersecurity defenses and resilience is paramount, given the persistent and evolving threat from state-sponsored actors. Diplomatically, maintaining open channels of communication with Beijing while clearly articulating red lines and upholding international law is essential to manage competition and avoid miscalculation. Economically, diversifying supply chains and developing robust anti-coercion strategies can mitigate the impact of China's expanding anti-sanctions toolkit. Finally, continued monitoring and analysis of China's military modernization, particularly in AI and advanced weaponry, are necessary to inform long-term defense planning and maintain a credible deterrence.
