China Security Report — June 26, 2026

Security analysis based on open-source intelligence and web research. Period: June 19 — June 26, 2026.

Executive Summary

China's security posture during the period of June 19-26, 2026, was characterized by heightened assertiveness in its maritime claims, particularly in the Taiwan Strait and South China Sea, alongside significant diplomatic and military developments. Beijing defended its recent coast guard patrols near Taiwan, which drew alarm from European nations, and continued its activities around disputed features like Scarborough Reef. Concurrently, China engaged in a tit-for-tat trade dispute with the United States, imposing export controls on US entities, while also seeking to stabilize relations with Washington following a recent summit. Domestically, the People's Liberation Army (PLA) leadership underwent intensive ideological training, underscoring a focus on political loyalty and military modernization amidst evolving regional and global dynamics.

Key Security Developments

• Heightened Maritime Assertiveness in the Taiwan Strait
  On June 26, China defended its recent patrols in waters east of Taiwan, following expressions of alarm from Britain, France, and Germany regarding "novel Chinese activity". This came as China sailed its newest and most powerful aircraft carrier through the Taiwan Strait, just hours after Taiwan commenced a five-day military exercise to practice its response to a potential Chinese attack. Earlier in the month, Chinese Coast Guard ships were reported harassing commercial vessels near the island by demanding their intended routes. Taiwan also condemned China on June 19 for conducting a marine survey in its exclusive economic zone (EEZ) off the east coast, with a Chinese research vessel, Xiang Yang Hong 22, escorted by two China Coast Guard ships, being expelled by the Taiwan Coast Guard.

• Escalation of South China Sea Disputes
  On June 21, concerns were raised over China's apparent installation of a floating structure at Scarborough Reef, a sensitive flashpoint in the South China Sea. This development triggered diplomatic protests from the Philippines and increased vigilance from allies and partners. Philippine officials had begun investigating reports of China deploying such a structure inside the lagoon of Scarborough Reef in late May 2026. The Armed Forces of the Philippines (AFP) tracked 82 Chinese coast guard and naval vessels within the Philippines' EEZ in May 2026, with 39 specifically around Scarborough Reef. Reports also indicated that China has resumed building artificial islands in the South China Sea after nearly a decade.

• Sino-US Trade and Technology Retaliation
  On June 26, China's Ministry of Commerce urged the United States to cease adding Chinese firms to its "military company list" and announced countermeasures. This followed China's announcement on June 22 that it would add 10 US entities, including rare earth and magnet developers MP Materials and USA Rare Earth, to its export control list, prohibiting the export of dual-use items from China to these companies. This move was positioned as a direct response to recent US actions targeting Chinese military-linked companies.

• PLA Ideological Training and Loyalty Reinforcement
  By June 25, China's top military brass, including generals, lieutenant generals, and major generals, completed a 10-week ideological training program focused on Xi Jinping Thought. This unprecedented exercise, personally decided by President Xi, aimed to ensure political loyalty and ideological alignment within the People's Liberation Army (PLA) amidst an ongoing anti-corruption drive.

• Naval Presence in the East China Sea
  On June 19, the Japan Maritime Self-Defense Force (JMSDF) observed a People's Liberation Army Navy (PLAN) Jiangkai-III-class guided-missile frigate (hull number 545) and a Fuyu-class fast combat support vessel (hull number 901) sailing northeastward approximately 140 km southeast of Miyako-jima Island. These vessels subsequently sailed northwestward through the waters between Okinawa Main Island and Miyako-jima Island into the East China Sea.

• Development of Advanced Air-to-Air Missile
  A report on June 22 highlighted the development of China's newest air-to-air missile, the PL-16, which experts believe could rival the US AIM-260 Joint Advanced Tactical Missile (JATM). The PL-16 is estimated to have a long total flight distance of 200 to 300 kilometers and features dual-pulse or variable-thrust rocket motor technology, potentially giving the PLA an advantage in Asia-Pacific conflicts.

• China's Vision for Global Governance
  On June 24, China published a white paper titled "More Just and Equitable Global Governance: China's Principles, Proposals and Actions," signaling its evolution from a participant to an architect of a new global order. The document advocates for a more genuinely multipolar order, the centrality of the United Nations, and greater influence for the Global South in setting global rules and priorities.

• Sino-Indian Relations Show Signs of Normalization
  On June 24, India and China held a meeting between their national security advisers in New Delhi, where both sides noted progress towards gradual normalization of their relationship. India's Ministry of External Affairs stated that the two leaders assessed progress in bilateral engagement and acknowledged advances made towards restoring normal relations.

• EU-China Trade Tensions and Diplomatic Snubs
  China unexpectedly canceled two high-level diplomatic meetings scheduled for June with the European Union, without providing an official reason. These cancellations, reported on June 12, occurred amidst growing trade tensions, with the EU recording its largest-ever trade deficit with China in 2025, reaching €360 billion. EU leaders met on June 19 to discuss a new China trade policy over concerns of a "systemic threat".

• US Military Posture in the First Island Chain
  On June 26, it was reported that the US is planning a longer-term presence of a Typhon midrange missile system in Japan, combined with the fielding of Navy-Marine Expeditionary Ship Interdiction System (NMESIS) anti-ship missiles and Marine Air Defense Integrated System (MADIS) air-defense systems by Okinawa-based units. This strategy aims to create a distributed network of strike, air-defense, and targeting capabilities to complicate Chinese military operations around Taiwan and across the western Pacific.

Geopolitical Impact and Regional Dynamics

China's actions during this period have significantly influenced regional stability and its relationships with major global powers. The increased assertiveness in the South China Sea and around Taiwan has exacerbated tensions with the Philippines, Japan, and European nations, who view China's maritime activities as destabilizing and a threat to freedom of navigation. The deployment of Chinese coast guard vessels and the installation of structures in disputed areas like Scarborough Reef directly challenge international rulings and sovereign rights, pushing regional claimants closer to the United States and its allies. The US response, including the planned deployment of advanced missile systems in Japan, signals a strategic shift towards a more distributed deterrence posture along the "first island chain," directly aimed at complicating Chinese military operations in the region.

Diplomatically, China's relationship with the United States remains a complex mix of cooperation and confrontation. While a recent summit between Presidents Xi and Trump aimed to establish a "constructive China-US relationship of strategic stability", the tit-for-tat export control measures underscore deep-seated economic and technological rivalries. China's welcoming of the US-Iran peace agreement, while potentially a move to project itself as a global peacemaker, also reflects its interest in regional stability that could reduce US influence. The cancellation of high-level meetings with the EU highlights growing friction over trade imbalances and industrial policies, indicating a potential divergence in economic relations with Europe.

The strengthening of the Russia-China strategic partnership, reaffirmed by Putin's May visit, continues to be a significant geopolitical factor. This alignment, rooted in shared opposition to Western dominance and a vision for a multipolar world, provides a counterweight to US-led alliances, particularly in the context of North-East Asia where both countries oppose Japan's re-militarization. However, China's new white paper on global governance, while advocating for a new world order, also reveals a cautious approach to financial commitments, suggesting that Beijing's global ambitions are balanced by domestic economic considerations. The gradual normalization of relations with India, as evidenced by the National Security Advisor meeting, could offer a potential avenue for de-escalation in a separate, yet critical, regional dynamic.

Military and Defense Analysis

China's military and defense strategy continues its trajectory of modernization and capability enhancement, backed by a substantial and steadily increasing defense budget. The 2026 defense budget saw a 7% increase, reaching approximately $277 billion, making it the second largest globally after the US. This funding is directed towards military salary increases, training, maneuvers around Taiwan, cyberwarfare capabilities, and advanced equipment purchases. Premier Li Qiang emphasized the goal of strengthening the military and undertaking major defense-related projects, with the fundamental aim of maintaining peace and safeguarding national sovereignty and development interests.

Force posture in the region reflects an increasingly assertive stance, particularly in maritime domains. The sailing of China's newest aircraft carrier through the Taiwan Strait and the sustained presence of coast guard and naval vessels in disputed waters like Scarborough Reef and Taiwan's EEZ demonstrate a strategy of "gray zone" operations and de facto control. These actions are designed to assert sovereignty claims and test the responses of regional actors and their allies. The PLA's focus on internal ideological alignment, as seen in the 10-week training for senior officers, indicates a strong emphasis on political control and loyalty to the Communist Party, which is deemed crucial for effective military command and execution.

Capability developments are evident in several areas. The reported development of the PL-16 air-to-air missile, with its extended range and advanced propulsion, suggests a focus on achieving air superiority and countering advanced US equivalents. Furthermore, Chinese researchers have detailed a strategy to "swarm" US carrier groups from 3,000 kilometers away using coordinated hypersonic anti-ship missiles, decoy drones, and cruise missiles, indicating a sophisticated approach to anti-access/area-denial (A2/AD) capabilities. While the US is adapting its posture with missile deployments in Japan to counter these capabilities, China's ongoing modernization efforts, including in submarine operations and undersea mapping, continue to enhance its ability to project power and challenge regional military balances.

Outlook and Forecast

Short-term trends (1-3 months): In the immediate future, China is likely to maintain its assertive maritime posture in the South China Sea and around Taiwan. We can anticipate continued "gray zone" operations, including coast guard patrols, marine surveys, and the potential for further infrastructure development on disputed features. Diplomatic rhetoric will likely remain firm on sovereignty issues, particularly concerning Taiwan and maritime claims. The trade and technology friction with the US is expected to persist, with both sides likely to implement further targeted measures. China will also continue to deepen its strategic coordination with Russia, potentially through joint military exercises or further economic integration, especially as it seeks to counter Western influence.

Critical flashpoints and risk areas: The Taiwan Strait remains the most critical flashpoint. Any perceived escalation by Taiwan or its allies, such as increased military cooperation with the US or a shift in its political status, could trigger a significant Chinese response, including large-scale military exercises or economic coercion. The Scarborough Reef and other disputed areas in the South China Sea are also high-risk zones, where incidents between Chinese and Philippine vessels, or those of other claimants, could quickly escalate. The planned deployment of US missile systems in Japan along the "first island chain" introduces a new layer of complexity and potential for miscalculation, as China views such deployments as a direct threat to its security interests.

Indicators to monitor: Key indicators to monitor include the frequency and scale of Chinese military and coast guard activities in the Taiwan Strait and South China Sea, particularly any new "law enforcement" operations or infrastructure developments. The nature and tone of diplomatic exchanges between China, the US, and EU, especially regarding trade disputes and technology restrictions, will be crucial. Any new announcements regarding China's defense spending, military modernization programs (e.g., new naval assets, missile tests), or the outcomes of high-level political meetings (e.g., with Russia, India) should be closely watched. Furthermore, the internal political stability within China, particularly any shifts in the emphasis on ideological purity within the PLA, could have implications for its external policies.

Strategic recommendations: For regional and international actors, a coordinated and consistent diplomatic approach is essential to deter unilateral actions by China in disputed territories. Strengthening multilateral security dialogues and mechanisms can help manage tensions and promote adherence to international law. Economically, diversifying supply chains and reducing reliance on single markets can mitigate the impact of trade disputes. Militarily, maintaining a credible deterrence posture, coupled with clear communication channels to prevent miscalculation, is vital. For China, a more transparent and rules-based approach to its maritime claims and a willingness to engage in constructive dialogue on trade and technology issues would contribute to regional and global stability.
