Introduction
The narrative of China’s national sovereignty and territorial integrity has shifted since Xi Jinping came to power in 2012–13. His staunch position on defending sovereignty and national borders introduced a new collective security framework that ties the security of land borders with the security of the high seas. The Chinese military’s recent coercive activities reveal that Beijing’s coercive activities against Taiwan and the Philippines can predict the future outcome of the India-China border.
This essay argues that China seeks to establish a “new normal” along the India-China border, similar to the Taiwan Strait and the South China Sea. On October 21, India announced a new patrolling pact that would allow troops to resume patrolling at Depsang and Demchok. Media reports suggest that buffer zones created in other areas will remain to reduce escalation chances. In December 2024, India’s foreign minister, Subrahmanyam Jaishankar, confirmed the disengagement of troops at key friction points. Following this announcement, New Delhi and Beijing held high-level talks to reduce military tensions, including a visit by India’s national security advisor (NSA), Ajit Doval, to China to resume the Special Representative talks.
This paper argues that despite the limited patrolling pact, the People’s Liberation Army’s (PLA) construction of dual-use infrastructure hasn’t slowed down and will continue. The large deployment of soldiers on both sides of the India-China border will be the “new normal.”
China is expanding the scope of its military exercises from the Western borders with India to the Taiwan Strait and the South China Sea. It violated Japanese airspace and waterways on multiple occasions in 2024, further adding a new dimension to regional tensions.
Regional tensions between China and its neighbors are unfolding against the backdrop of the U.S.-China great power rivalry, but the prognosis of China’s military coercion against its neighbors can be contextualized through the long-held dilemma of its military strategists.
Chinese military strategists have always been concerned about a “chain reaction” (liansuo fanying dai) of conflicts erupting at the border frontier. The strategists analyze this “chain reaction as a situation in which certain external powers would use a crisis over Taiwan to seize China’s territory along the western border. One set of Chinese military strategists argues that external powers, including India and the United States, could use the crisis over Taiwan as an opportunity to grab territory through a limited military operation. Others have suggested that external powers foment internal trouble in ethnic regions such as Tibet.
Xi Jinping’s recent speeches and military actions in the region can glean a new strategic framework that envisions securing China’s territorial sovereignty across all the military theatres.
Some experts have argued that China’s border dispute with India isn’t a priority for Beijing as the Taiwan contingency remains the number one strategic goal. The Taiwan Strait as the priority theatre for China remains broadly valid. However, China’s extensive dual-use military architecture along the Line of Actual Control (LAC) has set the stage for the long-term deployment of the PLA along the border with India to address security challenges that could emerge along the land border because of conflict in the Taiwan Strait or the South China Sea.
As the discussion about resolving the border stand-off grows, the PLA’s large deployment paints a different picture. China’s infrastructure and military build-up point toward a long-term deployment of PLA forces in Ladakh.
During the Qing era, Chinese military strategists articulated the security dilemma of balancing land defense with the need to defend the maritime space. The colonization of foreign concessions in the late eighteenth and early nineteenth centuries revealed the flaw in China’s military strategy as imperial dynasties had focused on land border defense.
Xi Jinping—and even his predecessor Hu Jintao—have attempted to address the West-East security dilemma. Xi has sought to create a framework through a network of dual-use infrastructure and near-permanent military deployment along the LAC to counter potential military adventurism along the land border, thus seeking to address a long-held strategic dilemma.
“We must coordinate the promotion of border, sea, and air defense construction and the economic and social development of border and coastal areas, strengthen the interconnection and co-construction and sharing of infrastructure, and create a border, sea, and air defense construction pattern that can effectively maintain security and strongly support development,” said Xi Jinping at a Politburo session in July 2024. The timing of this speech at the Chinese Communist Party’s Politburo Standing Committee on border, coastal, and air defense is significant. Coinciding with the ninety-seventh anniversary of the PLA, the address served as a high-profile signal of China’s resolve to deter perceived threats from the United States and its allies, including Taiwan. Beijing aims to reinforce its strategic deterrence posture amid increasing regional tensions by highlighting its commitment to defending sovereignty and territorial claims.
Blasko and Mei argue that Xi’s emphasis on homeland defense may increase funding for dual-use infrastructure projects in border regions, encouraging local governments to participate in national defense initiatives under the military-civilian fusion strategy.
For Xi, shaping the security situation along the border requires establishing a “new normal” (xīn chángtài). Since President Tsai Ing-wen assumed the presidency in Taiwan, China has sought to actively shape the security situation to establish this “new normal.”
Xi Jinping’s military modernization efforts since 2015 have pushed the PLA into a constant mode of exercise aimed at the 2027 military modernization target.
Through military exercises and deployments, China is creating a new normal to extend its sovereignty claims, which has put the PLA in a reactive mode along the LAC and the Taiwan Strait.
India-China Border
The India-China border stand-off is now in its fifth year as soldiers from the PLA and Indian Army continue to be deployed in Eastern Ladakh. Meanwhile, troops have disengaged from four locations after multiple military and diplomatic dialogues. Despite the limited patrolling pact in October 2024, which led to disengagement in Demchock and Depsang, the PLA soldiers remain deployed in large numbers at the two friction points, while other units are present in rare positions.
China’s ongoing infrastructure construction at the LAC means that even if there is disengagement at the remaining points, the PLA will likely remain in their new positions for the foreseeable future. The PLA has taken the approach of changing facts on the ground as it has done in the context of the Taiwan Strait and the South China Sea.
The PLA’s presence along the LAC is now to cement its claims on areas previously patrolled with a limited force posture. An open-source data analysis conducted for this paper has revealed that the PLA continued military exercises across Eastern Ladakh throughout 2023 and into 2024. An analysis of open-source data from Weibo and WeChat shows that military exercises in 2023, instead of taking a back seat amid border talks with India, continued unabated.
An analysis of the PLA-linked media shows that military units deployed across Eastern Ladakh remained in the exercise posture despite phased disengagement at four locations. The author’s own analysis of PLA incursions from March 2020 until October 2024 suggests that incursions saw military exercises of the PLA’s light, medium, and combined arms divisions.
The PLA has extensively advertised its exercises in the Karakorum region, both to signal its stance to India and to internally establish a narrative of conflict resolve to its military. While China may not conduct land incursions against India as it does in the aerial and maritime domain, the PLA remains in a nearly constant exercise mode along the Ladakh border, pausing only during the winter months.
In Eastern Ladakh, China has expanded the dual-use Ngari Gunsa Airport while beginning the construction of the dual-use Ngari Purang Airport. At least five new heliports have been built across the border, along with the construction of a new heliport in 2024. China has also built landing strips at ten other locations, which could be upgraded to a full-fledged heliport.
China’s dual-use infrastructure has been built to maintain PLA forces at the frontlines of Eastern Ladakh for the long haul. The infrastructure construction in Eastern Ladakh will cement the troops’ permanent presence, marking a new phase of military build-up that increasingly appears like China’s military installations in the South China Sea.
Blasko argues that the PLA’s deployment in the Aksai Chin region, which has an estimated 20,000 soldiers, may not be adequate to launch an attack; however, the presence of PLA soldiers is a long-term strategy to create “facts on the ground,” similar to its approach to changing the situation in the South China Sea.
Taiwan Strait
Military tensions in the Taiwan Strait have continued to escalate since former president Tsai Ing-wen assumed office in 2016. PLA aircraft, including bombers and fighters, circumnavigated Taiwan for the first time in July 2016.
Incursions into Taiwan’s Air Defense Identification Zone (ADIZ) increased to 1,703 in 2023. This author’s analysis suggests there was a rise in incursions into Taiwan’s ADIZ overlaps with the increasing land border violations at the LAC since 2016, especially following the Doklam stand-off in 2017. Data analysis by Greene et al. shows that incursions have markedly increased in the eastern sector along the border with India since 2016.
A gradual increase in PLA jets has also been reported in Taiwan’s ADIZ after the election of Taiwan’s current president Lai Ching-te in January 2024. The total number of PLA jets intruding into Taiwan’s ADIZ since January 2024 is over 2,200 jets.
In the case of Taiwan, ADIZ incursions have overlapped with political developments in Taiwan’s politics and U.S.-Taiwan relations under Tsai Ing-wen. However, a closer analysis of these incursions during Tsai’s presidency shows that they have become more random over time, primarily conducted for surveillance purposes. While India has faced sporadic clashes, Taiwan experiences near-daily air incursions aimed at normalizing the Chinese military’s presence. Randomizing the air incursions is a strategy to create a new normal in the Taiwan Strait while limiting the Taiwanese government’s response options. Taiwan’s defense minister Wellington Koo has expressed concern over the scale of the PLA’s military activity. He told reporters, “It is harder to discern when they [China’s military] might be shifting from training to a large exercise, and from an exercise to war.”
Beijing’s military coercive aims to constrain Taiwan and India’s geopolitical options by limiting their external balancing. China has shifted the narrative of defending borders from a maximalist approach to one of national sovereignty.
While increased intrusion into the Taiwanese airspace clearly correlates with significant political events, no such direct connection exists in the case of India-China tensions. However, China’s coercive actions against Taiwan—through the navy, coast guard, and the air force—seek to deter Taiwan from declaring independence and counter the growing cooperation between Taiwan and the United States.
Beijing has signaled the desire to change the status quo in the Taiwan Strait and the LAC to exert territorial claims. The military strategy for each theatre may be adjusted based on the history of territorial disputes in the Taiwan Strait, the South China Sea, or the India-China border. However, the strategic goal is to forge a new normal that will create a long–term strategic space dominated by China.
Tensions in the South China Sea
In 2013, China began constructing large islands in the South China Sea to project power and reinforce its claim of sovereignty over the disputed waters. It has since pushed further into areas claimed by the Philippines, increasingly confronting Filipino fishermen and the Philippine Coast Guard (PCG). Tensions have escalated since 2023, marked by clashes between the Chinese Coast Guard (CCG) and the PCG. The Philippines recently reported a record 251 Chinese vessels inside its territorial waters within a week.
China has empowered the CCG, including Coast Guard Law, to extend its territorial claims in the South China Sea. In 2023, the CCG rammed ships and used water cannons against PCG to restrict the Philippines’ ability to patrol its claimed waters—forcefully extending its territorial claims.
In September 2024, China conducted complex naval exercises in the South China Sea to deter growing maritime cooperation between the Philippines, the United States, Japan, and other allies. Some analysts have called China’s island construction a “salami-slicing” tactic that seeks to change the facts on the ground by extending territorial claims through infrastructure. However, through coercion and dual-use infrastructure, Beijing’s sovereignty claims seek to create a new strategic space along China’s territorial border—the “new normal.”
Conclusion
India, Taiwan, and the Philippines have faced increasing territorial coercion by the PLA since Xi Jinping assumed office. From his first term, Xi began articulating a sovereignty framework that sought to address a long-held strategic dilemma for Chinese military strategists.
Unlike the Taiwan Strait and the South China Sea, China has not extended a clear sovereignty claim to the Ladakh region. However, Beijing has taken a maximalist approach to sovereignty, including constructing dual-use infrastructure along the LAC. China has sought to establish a new normal on its territorial claims through coercion on the land border and the high seas.
Is China’s strategy to coerce its neighbor and limit its strategic options working? That’s a different debate. However, Beijing appears to have set its mind on creating a strategic depth to ensure long-term security in a turbulent international environment.
Therefore, disengagement in the remaining sectors of the LAC may not lead to an immediate de-escalation of tensions. The examples of Taiwan and the Philippines reveal China’s intentions to progress the land border issue with India into a Taiwan Strait or South China Sea-like scenario. The recently announced patrolling pact has the likelihood to flare tensions once again as the troops will now face each other during the patrols.
Through the “new normal,” China is forging a strategic depth along its borders to address historical and future security threats posed by neighbors, regional, and external powers.
India’s diplomatic position on resolving border disputes is heavily influenced by the resolution of past border stand-offs, such as the 2013 Depsang stand-off. The current military stand-off, however, is taking place under a different geopolitical environment and under a leader unwilling to compromise on sovereignty. Therefore, the much-desired disengagement and de-escalation at the India-China border will not solve the tensions between the two Asian powers.
