Asia's Cauldron: The South China Sea and the End of a Stable Pacific, is an interesting analysis of the South China Sea issues currently in the works, with a few notable flaws. The book is an excellent place to start on this issue, analyzing the broad strokes viewpoint from the positions of the United States, China, Taiwan, Singapore, Malaysia, Vietnam and the Philippines; basically all the major players in the South China Sea dispute.
For those unfamiliar with this issue, the South China Sea is a flashpoint for tension in the modern world, due to many conflicting claims over the small islands and atolls that dot the two million+ square miles of this region. All the countries listed above have overlapping claims with some or all of the states that ring the region in southeast Asia. China and Taiwan claim most of the region, using the infamous "nine-dash line" to denote their territorial claims, and basing these claims weakly on historical documentation, and more assertively with out-right control and policing of some of the zones. This has placed primarily China into political conflict with the above listed nations. These smaller states have turned to the United States to try and exercise some military control over the issue. They have also turned to international law to try to arbitrate the dispute in terms of the International Law of the Sea - a weak claim as their guarantor in the region, the US, has not ratified this agreement itself.
As can be seen, both China and some of the principle states in the region have confusingly weak claims on these islands, but covet them all the same due to the potential for offshore mineral resources, control of the valuable trade routes that pass through the region, and a nationalism driven by both present and historical issues. The key conflict in the region is between the US and China. The United States currently has the most powerful navy in the world, and uses this massive and overwhelming force to police the worlds Seas to ensure stable trade routes and to ensure its hegemonic presence. China on the other hand is a rising world power with historical regional hegemony that is trying to break free of its past embarrassments and present constraints in order to assert itself in the region and continue its rapid economic growth. This is the crux of Kaplan's argument: two world powers with conflicting interests and a whole lot of smaller states with regional interests, and Machiavellian power schemes. The states of Southeast Asia seek to keep the US tied into the region to ensure China will not make aggressive or foolish moves in the dispute. They do so by leasing space to the US military (Vietnam, Philippines and Singapore), by encouraging US businesses to set up shop (Singapore, Taiwan), and through cooperation and alliance building (all of the above). In the region, US power is the key counter-balance to a growing and more forceful Chinese state.
Kaplan takes a brief look at the policy stances inherent in each country, and is generally unbiased about the issue. He posits that the US navy is becoming increasingly weaker due to slashed budgets and conflicting politics at home, and that China's is becoming increasingly stronger due to its rapid economic growth and subsequent growth in military spending. China has few land-border disputes, and aside from its position on Korea, no longer needs a strong military on its many vast borderlands. This frees up funds for investment in naval growth, and China is moving swiftly in this direction. Their investment focuses on submarines, naval bases, carriers and militarized naval ships, as well as on conventional security forces, defensive weaponry and coast guard ships. China will approach the US in approximate naval strength in the Pacific region possibly by 2020 (as the US is tied up in patrolling other routes and involved in regional disputes in the Middle East). China has occupied and built military facilities on many of the disputed islands (as have most of the other states listed above), and uses civil coastal guard units as a tool to patrol waters, signaling its stance that those waters are "internal" issues. It's military is far larger than any of the other states (even combined), and so it also leaves the option of hard power open if needed. Its biggest tool, however, is its economic ties. Most of the above states are reliant on China for trade and investment, all the while exporting raw goods and materials to fuel China's economic growth. All the states above (including the US) have massive business investments in China and engage in trade and economic cooperation. This is China's biggest card - pulling away the carrot, and it has been known to utilize this at times (for example, the anti-Japanese riots during the Senkaku Islands dispute).
Kaplan has written an interesting book on the rising power of China in this region, and the declining power of the United States, and how this potential power shift may lead to a flare up between China and those reliant on US military presence to keep the status-quo in the dispute. However, the book suffers a few flaws. Kaplan's analysis seems a tad shallow, as he just touches the surface of the many issues the smaller Asian states face, but shies away from in depth fact finding. A good chunk of his information is based on journalistic interviews with unnamed officials from each country, giving an interesting, if suspect, source for information. Kaplan also looks deeply at the characteristics of each nation, based on historical trends and the past precedents of each nation - which adds a tinge of fluff to some of the analysis.
Kaplan has written an interesting and engaging - if shallow look at the South China Sea dispute in all of its complex glory. This book serves as a great introduction to the topic, but the lack of depth on each countries supporting claims, and facts surrounding their positions does do it a disservice. This makes the book highly readable due to its historical analysis and positing on geopolitical and strategic thought, but does have an air of bluster to it. Even so, it is certainly an interesting read, and I can easily recommend it for geopolitics junkies looking for a good, short book on an event that will continue to be reoccurring for the near future. The South China Sea is a potential flashpoint for regional or even global conflict, and it is an important dispute to understand if one is to gain a holistic viewpoint of Asian politics in the early 2000's. Give it a look if this interests you.
