It would be difficult to overstate the importance and timeliness of Scott Kastner’s Political Conflict and Economic Interdependence Across the Taiwan Strait and Beyond, which seeks to explain why, despite hostile political relations between Taipei and Beijing, economic ties have not only persisted, but accelerated.
Kastner, an assistant professor in the department of government and politics at the University of Maryland, goes far beyond the general, albeit contested, view that increased trade between two states reduces the likelihood of armed conflict. Rather, he argues that the more important question is when conflict affects trade. His main hypothesis is that national leaderships that are more accountable to “internationalist economic interests” are less likely to act in ways that threaten economic stability.
To make his case, Kastner looks at three protracted hostile political relationships, or dyads — Taiwan-China, India-Pakistan and South-North Korea — with emphasis on the Taiwan Strait. What follows is a fascinating exploration of the cross-strait paradox, whereby despite serious political conflict, trade between the two sides from the 1980s on has accelerated.
While prior to the mid-1980s economic interaction between Taiwan and China was extremely limited, democratization in Taiwan, added to a revaluation of the New Taiwan dollar that made domestic manufacturing less competitive, brought gradual changes in Taipei’s policies on investment in China. Democratization meant that the authorities became more accountable to the people and could no longer ignore business associations, or the “internationalist economic interests,” which gained clout as the size of the businesses investing in China grew. As liberalization intensified, the cost to the national leadership of ignoring those interests, or of preventing their expansion, increased.
This process went relatively smoothly, until the nature of the commercial links began having what Kastner calls “negative security externalities” for Taiwan. Arguments for caution included fears that investment in China helped it modernize, or that Taiwanese operating in China could be used for blackmail by Beijing, or held hostage. Furthermore, as trade intensified, Taiwan became increasingly dependent on China, which by the early 2000s surpassed the US as Taiwan’s primary trade partner.
Those security externalities forced the Taiwanese leadership to perform a balancing act between safeguarding political interests (e.g., sovereignty) and remaining accountable to business interests that not only called for further cross-strait trade liberalization, but also increasingly clamored for stability in the Taiwan Strait.
Taipei was therefore compelled to adopt a two-track approach to economic ties with China, one that clearly separated trade from politics. For Beijing, however, the growing cross-strait economic relationship had few negative externalities; it realized, in fact, that economic integration could be a crucial component of its ambition to annex Taiwan. To this end, in times of crisis it has sought to reassure Taiwanese businesses operating in China — including, with a few exceptions, “green” ones — that their interests are safe. As it stands to gain economically and politically from cross-strait economic integration, Beijing has refined the signals it sends to Taipei to express displeasure when the Taiwanese leadership appears to threaten the “status quo” so that Taiwanese business will not be scared off. Still, given the authoritarian nature of its government, in extreme cases Beijing is at greater liberty to act, even when its decisions risk undermining local governments that benefit from Taiwanese investment.
Kastner nevertheless shows that despite becoming increasingly beholden to business interests, Taiwanese leaders can slow the pace of integration when the domestic political conditions are right. As such, both Lee Teng-hui (李登輝) during his second term and Chen Shui-bian (陳水扁) during the 2004 elections were able to tap into sovereignty and protectionist constituencies to retain their grip on power, which had a cooling effect on cross-strait liberalization.
Still, one conclusion that can be drawn from Kastner’s book is that even when pro-independence administrations are in power, and even in times of high political tension across the Taiwan Strait, liberalization will proceed. Furthermore, as Kastner rightly points out, leaders and their coalitions can have very different interpretations of the negative security externalities involved in trading with China, as President Ma Ying-jeou (馬英九) has shown.
The author remains ambivalent about the impact of trade on conflict, concluding that its constraining (higher costs of war making it less likely) and transformative (reconciliation through increased contact) effects appear to have been marginal. Despite two decades of economic integration, for example, Taiwanese support for the “status quo” has remained constant. Ironically, international economic interests and China’s dependence on global markets may also have limited its ability to send threatening signals to Taipei, as doing so risks alarming international investors. Taipei, Kastner writes, may have been aware of this, which could account for risk-taking on the question of sovereignty. One constraining factor that Kastner oddly leaves out, however, is the security guarantees the US has extended to Taiwan.
Kastner concludes on a note of cautious optimism about the pacifying potential of economic liberalization in the Taiwan Strait. Still, he argues that if economic integration continues to accelerate — which the proposed economic cooperation framework agreement (ECFA), added to growing Chinese investment in Taiwan, would certainly do — future Taiwanese presidents may be less inclined, or able, to undermine stability for political reasons. This would indicate that we can expect more “centrist” government coalitions that are more accountable to business internationalists to be voted into office. The ramifications for the future of Taiwan as a distinct political entity, while serious, are not addressed by Kastner, who throughout his book remains commendably neutral, if not clinical, about his political preferences regarding the question of Taiwanese independence.
Given the idiosyncratic nature of the Taiwan Strait conflict, added to the unique nature of the political systems in Taipei and Beijing, it would be imprudent to generalize the findings by applying them to other conflicts (something Kastner admits himself). This said, Political Conflict and Economic Interdependence Across the Taiwan Strait is arguably one of the most important works of political science theory written about the Taiwan Strait in recent years and makes a substantial contribution to our understanding of political decision-making.
“Why does Taiwan identity decline?”a group of researchers lead by University of Nevada political scientist Austin Wang (王宏恩) asked in a recent paper. After all, it is not difficult to explain the rise in Taiwanese identity after the early 1990s. But no model predicted its decline during the 2016-2018 period, they say. After testing various alternative explanations, Wang et al argue that the fall-off in Taiwanese identity during that period is related to voter hedging based on the performance of the Democratic Progressive Party (DPP). Since the DPP is perceived as the guardian of Taiwan identity, when it performs well,
The Taiwan People’s Party (TPP) on May 18 held a rally in Taichung to mark the anniversary of President William Lai’s (賴清德) inauguration on May 20. The title of the rally could be loosely translated to “May 18 recall fraudulent goods” (518退貨ㄌㄨㄚˋ!). Unlike in English, where the terms are the same, “recall” (退貨) in this context refers to product recalls due to damaged, defective or fraudulent merchandise, not the political recalls (罷免) currently dominating the headlines. I attended the rally to determine if the impression was correct that the TPP under party Chairman Huang Kuo-Chang (黃國昌) had little of a
At Computex 2025, Nvidia CEO Jensen Huang (黃仁勳) urged the government to subsidize AI. “All schools in Taiwan must integrate AI into their curricula,” he declared. A few months earlier, he said, “If I were a student today, I’d immediately start using tools like ChatGPT, Gemini Pro and Grok to learn, write and accelerate my thinking.” Huang sees the AI-bullet train leaving the station. And as one of its drivers, he’s worried about youth not getting on board — bad for their careers, and bad for his workforce. As a semiconductor supply-chain powerhouse and AI hub wannabe, Taiwan is seeing
Jade Mountain (玉山) — Taiwan’s highest peak — is the ultimate goal for those attempting a through-hike of the Mountains to Sea National Greenway (山海圳國家綠道), and that’s precisely where we’re headed in this final installment of a quartet of articles covering the Greenway. Picking up the trail at the Tsou tribal villages of Dabang and Tefuye, it’s worth stocking up on provisions before setting off, since — aside from the scant offerings available on the mountain’s Dongpu Lodge (東埔山莊) and Paiyun Lodge’s (排雲山莊) meal service — there’s nowhere to get food from here on out. TEFUYE HISTORIC TRAIL The journey recommences with
