South China Sea Week Wraps up on CIMSEC

By Dmitry Filipoff

Last week CIMSEC featured an insightful series of publications in response to a call for articles soliciting analysis on the South China Sea. Contributors assessed the Permanent Court of Arbitration’s ruling on Philippines vs. China, evolving military developments, strategic perspectives, and more. We thank our authors for their excellent contributions. 

Below is a list of the articles that featured during the topic week, and revealing excerpts.

The Scholar as Portent of Chinese Actions in the South China Sea by Ryan D. Martinson

“Studying the work of the propagandist has merits: we learn what the PRC wants domestic and international audiences to believe. The statements of the advisor, however, are potentially much more rewarding, for they may suggest future actions.”

Assessing the Military Significance of the South China Sea Land Features by Ching Chang

“Whether these land features may contain military value significant enough to be fought for are never decided by themselves. Other factors such as force, timing and additional characteristics associated with the space will fundamentally define their importance.”

Sea Control 122 – The PCA Ruling with CAPT James Fanell by Sally DeBoer

“But from an international law perspective and what most of the world accepts – China’s actions in the SCS were unilateral, aggressive, and threatening to their neighbors. This ruling states that this behavior is not correct and that this is not an accepted way to act in the international community.”

The Undersea Dimension of Strategic Competition in the South China Sea by Elsa B. Kania

“Historically, China has remained relatively weak in ASW and continues “to lack either a robust coastal or deep-water anti-submarine warfare capability,” according to the Department of Defense.1 Despite such persistent shortcomings, the apparent advances in the realism and complexity of these recent drills suggest that the PLAN’s ASW capabilities could be progressing.”

“On the one hand, the United States sees freedom of navigation as a fundamental pillar of the post-war order and integral to the past 70 years of relative peace and prosperity. On the other, China’s (re)assertion of sovereignty over the South China Sea should be contextualized within its century long campaign to recover territory lost under (semi)-imperialism.”

Clash of Core Interests: Can One Mountain Hold Two Tigers? 核心利益的冲突:一山,不容,二虎?

South China Sea Topic Week

The following article is published in English and Chinese. 

By Tommy Jamison

The present dispute over the South China Sea doesn’t hinge on fishing rights, or oil fields, or even military bases. At its root the controversy stems from conflicting, profoundly held and historically consistent “core interests/核心利益.” On the one hand, the United States sees freedom of navigation as a fundamental pillar of the post-war order and integral to the past 70 years of relative peace and prosperity. On the other, China’s (re)assertion of sovereignty over the South China Sea should be contextualized within its century long campaign to recover territory lost under (semi)-imperialism. The historical grounding of both these arguments seems lost on much of Washington as well as Beijing. 

目前南海冲突的关键不是捕鱼权,不是油田,甚至也不是军事基地。从根本上讲,南海争议来源于不同的,有历史一致性的的核心利益。在一方面,美国认为航行自由是实现与二战以来持续七十年的安全与繁荣的重要基础。反过来,中国对南海的领土的主张跟其具有一百多年来“反殖民主义”的历史经历有很大的关系,我们应该思考这一背景。华盛顿跟北京一样,似乎都对双方的历史情况漠不关心。

Territorial controversies are not new in China. From the Opium War (1839-42) to the present, resisting imperialism and recovering lost territory have constituted core objectives of Chinese foreign policy. As such, it is only through first exploring this historical context that we understand the modern conflict in the South China Sea. Because of “Western” (semi)-imperialism, territorial disputes in Chinese modern history are very common and have profound political ramifications. The question of Shandong’s sovereignty was the fuse for the May Fourth movement (1919); Japan’s aggression in Manchuria (1931) led to the collapse of the post-WWI internationalist system and incited the Second World War; before 1997 Hong Kong was one of the world’s last formal colonies; today Sino-Taiwanese relations remain a powder keg, and so on. From this historical perspective of course the South China Sea is a sensitive question. It is also in some ways a legacy of resistance to imperialism and, to a certain extent, a continuation of the 20th century movement to recover lost territories.

中国的领土争议由来已久。从鸦片战争至今,反殖民主义与收复失地可以说是中国外交的核心目标之一。因此,我们首先要了解近代中国的历史背景,唯有如此,才能更好地了解现在的南海矛盾。由于西方帝国主义,在中国近代历史上类似的领土问题中无处不在,并产生深远的政治影响。山东省的主权问题是五四运动(1919)的导火线;日本在东北的侵略导致了一战后国际秩序的崩溃,也引发了第二次世界大战;1997之前,香港算世界上最后的正式殖民地之一;今天两岸关系还是一个“火药桶”等。从历史脉络的角度来看,南海主权理所当然是一个敏感的政治话题。同时,从某种角度上是反殖民主义的精神遗产,而且在一定程度上是二十世纪主权运动的继续。

At the same time, from a macroscopic perspective, the U.S. post-war diplomatic strategy can be summarized in four principles: 1) defend democratic regimes; 2) encourage free trade; 3) protect freedom of navigation, because it is a fundamental requirement of free trade (alongside today freedom of information, the skies and even space); and 4) spread liberalization, an admittedly abstract principle. In short, the U.S. post war strategy has been an attempt to replace the pre-war anarchic international system with a liberal internationalist system. China’s activity in the South China Sea threatens these aims, particularly freedom of navigation, and thus threatens the post-war international system. Freedom of navigation is often criticized in mainstream Chinese media, as in, “At root, freedom of navigation is an excuse to implement the ‘pacific rebalance’ strategy and to contain the emergence of China,” but the present world was developed from these ideals. As such, freedom of navigation is in no way an empty slogan, but rather a core U.S. interest.

与此同时,在宏观层面上,美国二战后的外交战略可以归纳为四个原则:一是保护民主政府;二是推动自由贸易;三是捍卫航行自由,因为航行自由是贸易自由最基本的要求,现在这个原则扩展到飞行自由、信息自由,甚至天空自由等范围。第四个原则是最抽象的——普及自由化。简而言之,美国二战后的战略试图用自由国际秩序来代替二战前的无政府国际秩序(anarchic international system)。如今,中国在南海的行为威胁到了这些原则,特别是航行自由,因此也威胁到了二战后的国际秩序。中国主流媒体常常讽刺航行自由,比如“归根结底是借推行航行自由之名,行推进亚太再平衡战略、遏制中国崛起”等,但是目前的世界格局正在这理念之上发展而来。因此,航行自由绝非一个凭空的口号,而是一个核心利益。

None of this is to say that today’s South China Sea controversy is a direct continuation of China’s resistance to imperialism—far from it—but only to suggest that the conflict’s acuteness cannot be divorced from a larger historical context. When writing his history of Sino-U.S. relations from 1989-2001, David Lampton appropriated a saying about spousal conflict to sum up his findings: Same Bed, Different Dreams (同床异梦). That’s about right for the South China Sea as well. Still, the more worrying phrase might be the oft heard, “one mountain cannot hold two tigers” (一山,不容,二虎), which not coincidently frames the last chapter of Sarah Paine’s excellent history The Wars for Asia (1911-1949). Given the significance of historical context in this dispute, the potential for the misuse of history is likewise apparent. Eric Hobsbawm once wrote, “Historians are to nationalism what poppy-growers in Pakistan are to heroin-addicts: we supply the essential raw material for the market.” That danger seems particularly applicable to South China Sea where the trends of nationalism, hegemony, ecological scarcity and globalization intersect.

Still, one thing is for sure, giving serious thought to the historical background informing behavior on both sides of the Pacific would go a long way toward dispelling the distortions of modern day nationalists and bureaucrats alike. It might even help prevent an especially unnecessary war.

The Undersea Dimension of Strategic Competition in the South China Sea

South China Sea Topic Week

By Elsa B. Kania

As the South China Sea dispute continues to command headlines, such issues as China’s island building, U.S. Freedom of Navigation Operations (FONOPS), and the contested arbitration have received justified attention, but a concurrent trend in the activities of the PLA Navy (PLAN) in the South China Sea also merits closer consideration. Within the past several months, the PLAN’s South Sea Fleet (南海舰队) has engaged in relatively sophisticated anti-submarine warfare (ASW) drills (反潜作战演练). Historically, China has remained relatively weak in ASW and continues “to lack either a robust coastal or deep-water anti-submarine warfare capability,” according to the Department of Defense.1 Despite such persistent shortcomings, the apparent advances in the realism and complexity of these recent drills suggest that the PLAN’s ASW capabilities could be progressing. Given the context, these drills, which were reported upon in detail in official PLA media,2 might also have been intended as a signaling mechanism at a time of heightened regional tension. Presumably, the PLAN is also motivated by concerns about U.S. submarines operating in the region and the submarines procured by multiple Southeast Asian nations, including rival claimant Vietnam.

While China’s ongoing investments in ASW platforms have indicated an increased prioritization of improving its ASW capabilities, the PLAN’s ability to advance in this regard will also be influenced by its level of training and experience.3 Certainly, the levels of stealth and sophistication of current and future U.S. submarines will continue to pose a considerable challenge. Although the PLAN’s ASW capabilities will likely remain limited in the short term, its attempts to realize advances in ASW reflect a new aspect of its efforts to become a maritime power and attempt to achieve “command of the sea” (制海权) within the first island chain.4

Recent PLAN ASW Drills in the South China Sea

Between May 25th and 26th, the PLAN’s South Sea Fleet engaged in ASW drills that involved a confrontation between Red and Blue Forces that continued “successively for twenty-four hours uninterrupted.”5 After entering the South China Sea through the Bashi Channel, within the Luzon Strait between Taiwan and the Philippines, the far sea training formation involved initiated the drill “under actual combat conditions.”6 The Red Force involved four surface warships, two Type 052D guided-missile destroyers (Hefei and Guangzhou), a Type 052C destroyer (Lanzhou), and a Type 054A guided-missile frigate (Yulin), as well as three unspecified anti-submarine helicopters, against a Blue Force with an unknown number of submarines.

Since anti-submarine operations have reportedly become a “key emphasis” (重点) for the South Sea Fleet, this constituted an attempt to design a more advanced, realistic drill for ASW operations.7 It was characterized as “really rare” given the large size of the search area (1,000 square nautical miles); the multiple forms of anti-submarine forces included; the multiple ASW methods used, including five kinds of sonar; the employment of a greater number of anti-submarine attack weapons including anti-submarine rockets, depth charges, and torpedoes, and finally the length of the drill, which occurred for 24 hours continuously.8 That these aspects of the drill were considered so notable implies that prior drills were appreciably less sophisticated. 

Although the drill seemed somewhat more advanced than previous such exercises, PLA media commentary also highlighted the existing shortcomings in the PLAN’s ASW capabilities that the drill was intended to mitigate. According to one PLAN officer who had participated, difficulties included the command and control over and coordination among the forces involved. He also highlighted that the two forces had not established a set program or plan prior to the drill – implying that past drills had been organized around more of a “script” (脚本).9 This lack of a script enabled the whole process to “break through into actual combat confrontation” and “explore anti-submarine methods and approaches.”10 In particular, this realistic training was intended to address certain “important difficulties,” including coordination between ships and aircraft, coordination of firepower, and information-sharing.11 For instance, a Blue Force submarine engaged in evasive measures, such that the Red Force had to cooperate closely and engage in real-time information sharing to locate it again and enable the launching of “precision strikes” against it.12

Although it is difficult to compare this ASW drill to previous iterations qualitatively or quantitatively – given the limitations of available information and uncertainties about the consistency of open-source reporting on such training – a review of prior accounts of the PLAN’s ASW exercises suggests that these drills have advanced considerably within the past several years. There seemingly has been a shift in the PLAN’s ASW training, starting from relatively routine exercises held only annually in the South China Sea, towards these more advanced exercises. In this regard, the South Sea Fleet’s engagement in this ASW drill at a time of heightened tension in the South China Sea not only might have been intended to serve as a signaling mechanism, but also may have reflected a longer-term trend toward advances in the PLAN’s ASW training. In the past several years, the PLAN’s ASW drills in the South China Sea have included the following:

  • September 2013: In accordance with the PLAN’s annual training plan, the East Sea Fleet held training exercises in the South China Sea that involved unspecified “new type” submarines, with collaboration between anti-submarine ships and anti-submarine helicopters, which reportedly “effectively increased ASW capability under informationized conditions.”13
  • September 2014: In accordance with the PLAN’s annual training plan, the East Sea Fleet held training exercises in the South China Sea in which there was an emphasis on “testing and exploring anti-submarine tactics.”14
  • May 2015: The Sino-Russian “Joint Sea” exercise incorporated an ASW component.15
  • November 2015: The North Sea, South Sea, and East Sea Fleets all engaged in live-fire “confrontation drills” in the South China Sea, involving Blue and Red Forces, which emphasized “information systems of systems ASW capability.”16, 17
  • January 2016: PLAN exercises with the Pakistan Navy incorporated ASW for the first time.18
  • May 2016: A sophisticated, realistic drill involving the South Sea Fleet occurred in the South China Sea, as described in detail above.19
  • July 2016: The PLAN’s extensive exercises in the South China Sea, which involved all three fleets, also included an ASW component.20, 21

While the list above is probably not comprehensive, this sequence seems to illustrate a potential shift in the pattern of the PLAN’s ASW training – or, at least, in official PLA media reporting on these drills. From late 2015 to the present, the reported drills have not occurred in accordance with the prior training schedule and have often involved the South Sea Fleet or multiple fleets. Perhaps this change indicates a shift in focus towards advancing the operational ASW capabilities of the South Sea Fleet in particular. As this timeframe has aligned with heightened regional tensions, the organization of such drills and the reporting on them could have indicated an increased degree of discomfort with the potential intensification of U.S. submarine activity in the South China Sea and also the ongoing procurement of Kilo-class submarines by rival claimant Vietnam, which received its fifth of six submarines in February 2016.22, 23 Eventually, this focus on realistic, unscripted ASW drills could enable the PLAN to progress in capitalizing upon the more advanced ASW platforms that have been concurrently introduced.

Ongoing Investments to Overcome Traditional Weaknesses in ASW

Although the PLAN’s ASW capabilities have historically been lacking, the increased frequency and sophistication of ASW drills have corresponded with investments in and the commissioning of new ASW platforms within the past several years. The PLAN previously had only the Ka-28 and the Z-9C as ASW helicopters, but has introduced the more sophisticated Changhe Z-18F ASW variant.24 Notably, the Y-8FQ Gaoxin-6, an anti-submarine patrol aircraft reportedly analogous to the P-3C, which has a lengthy magnetic anomaly detector, was introduced into the PLAN in 2015.25 Although it was not reported to have participated in recent exercises, the Gaoxin-6 could critically contribute to China’s future ASW capabilities. In June 2016, the PLAN’s South Sea Fleet also commissioned the Type 056A corvette Qujing, the tenth such vessel assigned to it, which reportedly has “good stealth performance” and has been upgraded with a towed array sonar for ASW.26, 27 As of 2016, a total of twenty-six Type 056 corvettes are in service throughout the PLAN, and there might eventually be sixty or more, likely including quite a few of this ASW variant.27

Beyond these existing platforms, the PLAN has been investing in multiple aspects of its ASW capability that could have significant long-term dividends. According to one assessment, the construction of a helicopter base on reclaimed land on Duncan Island in the Paracels could constitute a component of a future network of helicopter bases that would enable the PLA’s ASW helicopters to operate more effectively in those contested waters.29 The PLA’s existing and future aircraft carriers could launch multiple anti-submarine aircraft, and less-authoritative Chinese media sources have emphasized the expected efficacy of a future Chinese carrier strike group in ASW.30, 31 Concurrently, China has been establishing an underwater system of ocean floor acoustic arrays in the near seas, referred to as the “Underwater Great Wall Project” by the China State Shipbuilding Corporation responsible for its construction.32, 33 In addition, the PLAN clearly recognizes the relevance of unmanned surface vehicles (USVs) and unmanned underwater vehicles (UUVs) in ASW. For instance, PLA academics from China’s National Defense University characterize “unmanned operations at sea” as among today’s “important development trends.”34 There are multiple Chinese USVs and UUVs under development,34 and PLA-affiliated individuals and institutes have evidently engaged in extensive research on the topic.36

Conclusion

Although the operational potential associated with such investments might require years to be actualized, China could eventually become a significant ASW force in the South China Sea and beyond. While the PLAN’s ability to engage effectively in ASW will likely remain limited by persistent shortcomings and its relative lack of experience for the short term, it is nonetheless notable that the PLAN has evidently decided to compete in an area of traditional U.S. advantage, which had previously seemed to be a lower priority for it. These apparent advances in its ASW drills and increased investment in a variety of ASW platforms could allow the PLAN to become an inconvenience and eventually an impediment to the ability of other regional players, and perhaps even U.S. submarines, to operate unchallenged in the South China Sea. Thus far, the PLAN appears to be focusing primarily on near seas ASW, especially with the “Underwater Great Wall,” and this concern regarding defense within the first island chain could reflect a reaction to the intensified U.S. focus on submarines as a tool to counter China’s A2/AD capabilities.37

This undersea dimension of strategic competition will likely continue to be a priority for the U.S. and China alike, and the South China Sea will remain of unique strategic importance. Notably, the majority of China’s submarines, including its SSBNs, is based on Hainan Island and would probably transit to the Pacific through the South China Sea.38 While the prevailing “undersea balance” seems unlikely to change significantly in the near future,39 the PLAN’s undersea warfare capabilities could advance more rapidly than anticipated across multiple dimensions. For instance, by one assessment, China’s new Type 093B SSN could be stealthier than expected.40  Looking forward, the traditional dynamics could also be appreciably altered by technological change. In particular, the U.S. and China’s parallel advances in unmanned systems, which will likely play a significant role in future undersea warfare, could accelerate competition in this domain. While visiting the USS John C. Stennis in the South China Sea, Secretary of Defense Carter alluded to the Pentagon’s investment in “new undersea drones in multiple sizes and diverse payloads that can, importantly, operate in shallow water, where manned submarines cannot,” which could become operational within the next several years.41 The PLAN’s USVs and UUVs might not be far behind. Although the PLAN may prove unable to overcome the U.S. Navy’s undersea dominance beyond the first island chain, the South China Sea itself could become a zone of “contested command” and frequent undersea friction in the years to come.42
