When Stanford sociologist Gi-Wook Shin left his home country of South Korea in 1983 to pursue graduate studies at the University of Washington, he was certain he would return to Korea upon graduation. More than 40 years later, Shin, the William J. Perry Professor of Contemporary Korea and a senior fellow at the Freeman Spogli Institute for International Studies, is still in the United States. 

Yet he does not consider himself a case of brain drain for Korea. Shin, who is also the founding director of the Korea Program at the Shorenstein Asia-Pacific Research Center (APARC) and APARC director, has continuously contributed to Korea by leading transnational collaborations, researching and publishing on pressing issues in Korean affairs, and otherwise engaging in diverse intellectual exchanges with the country.

Shin’s experiences sparked his interest in the sociological patterns of mobile talent and a central question: How do countries attract, develop, and retain talent in a globalized world? His new book, The Four Talent Giants (Stanford University Press, 2025), explores that question regarding transnational talent flows from a comparative lens by examining how four strikingly different Asia-Pacific nations – Japan, Australia, China, and India – have become economic powerhouses.

The book’s main idea, Shin explains, is that how countries manage talent is key to their strength and future success. He calls the four Asia-Pacific nations the book examines “talent giants” because each has used a distinct talent strategy that has proven critical to national development. Three of these nations – China, Japan, and India – are among the top five economies in the world in terms of GDP, and Australia, despite its relatively small population size, is third in terms of wealth per adult.

In The Four Talent Giants, Shin investigates how these four nations have become global powers and sustained momentum by responding to risks and challenges, such as demographic crises, brain drain, and geopolitical tensions, and what lessons their developmental paths hold for other countries.

A New Framework for Studying Human Resource Development 

Asia’s robust economic growth over the past forty years is nothing short of a remarkable feat. The Asia-Pacific today continues to be the world's fastest-growing region, despite global economic uncertainty. How did this phenomenal ascendance come about?

The existing literature has emphasized common “recipes” of success among Asia-Pacific powers. Endeavoring to find one-size-fits-all formulas that could be replicated in other countries seeking rapid development, it has overlooked the distinct developmental journeys of Asian nations. “We need a new lens, or framework, to explain their successes, while also accounting for cross-national variation in development and sustainability,” writes Shin. 

In his book, Shin examines talent – the skilled occupations essential to a nation’s economy – as a key driver of economic development. While all countries rely on human resources for development, their talent strategies vary based on historical, cultural, and institutional factors. Shin introduces a new framework, talent portfolio theory (TPT), inspired by financial portfolio theory, to analyze and compare these national approaches.

“TPT views a nation’s talent development, like financial investment, as constructing a ‘talent portfolio’ that mixes multiple forms of talent – domestic, foreign, and diasporic – adjusting its portfolio over time to meet new risks and challenges,” he explains. Just as an investor may select different financial products in a mix of assets, countries can create talent portfolios by picking from various strategies.

Shin identifies four main strategies by which a country can harness talent – what he calls the four B's: 

• “Brain train” signifies efforts to develop and expand a country’s domestic talent or human capital.
• “Brain gain” refers to attracting foreign talent to strengthen the domestic workforce.
• “Brain circulation” involves bringing back nationals who have gone abroad for work or study.
• “Brain linkage” means leveraging the global networks and expertise of citizens living overseas through transnational collaboration.

Shin uses TPT as an analytical framework to examine how each of the four talent giants has constructed its distinct national talent portfolio and how this portfolio has evolved. As in an investment portfolio rebalancing, a nation can maintain diversification across the four B's and within each B. TPT therefore offers a holistic framework for understanding the overall picture of a country’s talent strategy, and how and why it may “rebalance” its talent portfolio.

Throughout the book, Shin shows that, while Japan has relied on the brain train strategy, Australia, whose population was too small for such an approach, emphasized brain gain. China used brain circulation: it first sent students and professionals abroad to learn, then implemented policies to encourage them to return. India, by contrast, established linkages among its diaspora and used them to develop its economy.

New Geopolitics of Global Talent: Lessons and Policy Implications

The case studies of the four talent giants reveal that there is no single path to talent-driven development. Each of the four Asia-Pacific countries has built its unique talent portfolio, balancing human and social capital, homegrown and foreign-educated individuals, and domestic and diasporic talents. While the talent giants use all four B's to some extent, each emphasizes them differently, reflecting diverse strategies and development paths. The core findings of these studies offer valuable insights for countries aiming to design effective talent policies. 

The four B's were instrumental in the economic rise of the four Asian nations, and they will be equally critical in addressing new challenges facing all economies, from demographic crises to emergent geopolitical tensions. For the United States, one such challenge is its sprawling competition with China, where the battle for talent is heating up in the race for technological supremacy.

Shin warns that the advantage the United States has long held in technological innovation, driven by its ability to attract skilled foreign talent, is now at risk from the Trump administration’s anti-immigration policies, pressures on universities, and cuts to research funding. “Immigrants have not just filled jobs,” he emphasizes. “They have created new industries and helped the US and their home countries. If the US makes it harder for talent to come in and stay, it risks hurting its long-term success.”

The Four Talent Giants is an outcome of Shin’s longstanding project investigating Talent Flows and Development, now one of the research tracks he leads at the Stanford Next Asia Policy Lab (SNAPL), which he launched in 2022. Housed at APARC, the lab is an interdisciplinary research initiative addressing Asia’s social, cultural, economic, and political challenges through comparative, policy-relevant studies. SNAPL’s education mission is to cultivate the next generation of researchers and policy leaders by offering mentorships and fellowship opportunities for students and emerging scholars.

Shin notes that the SNAPL team illustrates all four B’s in his talent portfolio theory, as some members are U.S.-born and trained, some come from Asia and, after working at the lab, return to their home countries, whereas some stay here, promoting linkages with their home countries. “In many ways, this project shows what is possible when we invest in talent and encourage international collaboration.”

Korea's Future Depends on Securing Global Talent
The Korean Daily, July 13, 2025 (interview)

This blog post was first published by the Australian Strategic Policy Institute's The Strategist analysis and commentary site.

The Quad is stronger than ever. The informal ‘minilateral’ grouping of Australia, India, Japan and the United States has in the past year held its first stand-alone ministerial meeting and its first leaders’ summit, and launched an ambitious project to deliver Covid-19 vaccines. This ‘golden age’ of the Quad is a product of newfound Indian enthusiasm for the grouping, in turn, spurred by the military crisis in Ladakh, where India faces ongoing Chinese troop incursions across the two countries’ disputed border.

But the Quad is not bulletproof. Some experts have suggested that the economic and diplomatic effects of the devastating second wave of the pandemic in India will preoccupy the Indian government, sapping the Quad of capacity for any new initiatives. Others counter that India remains committed to competition with China—which is what really matters for the Quad—although its partners always expected ‘two steps forward, one step back’ from India.

The pandemic may well prove to be a hiccup in the Quad’s evolution, but a potentially much larger disruption may come from the ongoing Ladakh crisis itself. As I argue in a new ASPI Strategic Insights paper, the crisis has greatly increased the risk of a border war between India and China, which would present a defining test of the Quad. A possible war could either strengthen or enervate the Quad—depending on how India and its partners, including Australia, act now to shape the strategic environment.

Risk is a function of likelihood and consequence. The likelihood of war on the India–China border is still low—both countries would prefer to avoid it—but has risen since the crisis began. Both countries have greatly expanded their military deployments on the border and backed them with new permanent infrastructure to resupply and reinforce them. China has proved its revisionist intent with large and costly military incursions, although its specific objectives and plans remain unknown. And the interaction of both countries’ military strategies and doctrines would, on the threshold of conflict, promote escalation.

The consequences of a possible conflict would be dire for both belligerents and for the region. China — assuming it is the provocateur of conflict—would likely face some political rebuke from states that consider themselves its competitors, but it will work strenuously to reduce those costs, and would likely have priced them in to its calculations of whether to fight. India will suffer high tactical costs on the border, and may also suffer wider harm if China uses coercive cyberattacks against strategic or dual-use targets.

In a costly war, the repercussions may spill over to damage India’s recently developing strategic partnerships, especially with the United States and Australia. Despite generally favorable views of the US, the Indian strategic elite still harbors some latent suspicions. This was highlighted in two episodes in April 2021, when the US Navy conducted a freedom of navigation patrol through the Indian exclusive economic zone, and when the US was slow in delivering Covid-19 vaccine raw materials and other relief. Both instances quickly receded from the Indian public imagination—thanks to quick correctives from Washington—but they did reveal that, under some conditions, Indian perceptions of its new partnerships can be quickly colored by distrust.

A China–India border war may create exactly those conditions. There is a chance that conflict may result in a redoubled Indian commitment to the Quad, if New Delhi judges that it has no option but to seek more external assistance. Conversely, unless a conflict is managed well by India and its partners, it is more likely to result in Indian disaffection with the Quad. India deepened Quad cooperation during the Ladakh crisis partly as a deterrent signal to China, and partly because the Quad is still full of promise. However, after a conflict—when China hasn’t been deterred and has probably imposed significant costs on India—the Quad’s utility would have been tested, and probably not ameliorated India’s wartime disadvantage.

The task before Quad governments is to be sensitized to this risk and implement mitigation strategies before a possible conflict, to buttress the coalition in advance. As I outline in the ASPI paper, they could do this at three levels. First, they could offer operational support—such as intelligence or resupply of key equipment, as the US already has done in the Ladakh crisis—although Quad partners’ role here would be limited. Second, they could provide support in other theatres or domains—with a naval show of force, for example, although cyber operations would probably be more meaningful in deterring conflict or dampening its costs. Third, they could provide political and diplomatic support — signaling to Beijing that a conflict would harm its regional political standing.

For Quad members, the main goal would be to deter conflict in the first place, and, failing that, to preserve the long-term strategic partnership with India for the sake of maintaining as powerful and energetic a coalition as possible to counterbalance China in the long term.

This op-ed by Oriana Skylar Mastro and Zack Cooper originally appeared in Australian Financial Review.

Australia’s trials are not the first time Beijing has used economic coercion against another country.

It has become so common that we are becoming desensitised to it. Some notable examples include Beijing’s limitations on rare earth exports to Japan in 2010, Norwegian fish exports in 2010, Philippine tropic fruit exports in 2012, Vietnam’s tourist industry in 2014, Mongolian commodities trade in 2016, and South Korean businesses in 2017. In each case, Beijing sought to achieve a political objective by imposing economic penalties.

This case is different. Beijing has typically been ambiguous about the purpose or nature of its coercive economic statecraft. Despite evidence otherwise, it blamed the Japanese ban on meeting a yearly quota, the Philippine ban on pesticide exposure, the tourism drop to Vietnam on changing Chinese preferences, and the closure of South Korean stores on fire code violations. In Australia’s case, though, Beijing is doing away with these pretenses.

China has not been shy this time about connecting its punitive actions to its unhappiness with Australian policies. The Chinese foreign ministry has listed a “series of wrong moves” by Australia for the disruption in relations. Beijing’s embassy in Canberra then gave a list of 14 “mistakes” to the Australian press.

These grievances include Australia’s foreign interference legislation, foreign investment reviews, funding for Australian think tanks, and unfriendly media reporting. Some of these criticisms are particularly ironic coming from Beijing, which often objects to foreign interference in other countries’ domestic affairs.

A core component of China’s strategy is a disinformation and propaganda effort designed to paint its moves as merely defensive, a proportionate and legitimate response to actions taken by the other side.

Australia has done nothing ‘wrong’

Let’s be clear: Australia has done nothing “wrong” in promoting and protecting its democratic institutions at home. It should not censor its media, obstruct analysis by outside experts, or shy away from safeguarding its democratic processes.

This time, the current trade restrictions are about more than making an example of Australia or showing smaller powers that they’ll pay if they have something to say about how the Chinese Communist Party governs at home. Beijing’s aims have taken on new proportions. Party leaders are now willing to punish democracies simply for upholding basic democratic principles within their own countries.

The message is clear: curtail some of your democratic principles or pay the price.

The US needs to work with like-minded states around the world to address this new threat. Free countries need to speak out together in Australia’s defence. If democracies do not hang together, they will hang separately. We should articulate that China’s actions are more than a violation of international law; they threaten the health of our democracies at home. Such a reframing would show Beijing that economic coercion will no longer be treated as a low-stakes tactic.

But words are not enough. We need coordinated action. US alliances are designed primarily to deter and defend against military attacks. Chinese actions make clear, however, that there are alternative methods for undermining peace, prosperity and freedom that our alliances do not adequately address. New alliance consultations to protect against economic attack would enhance our deterrence against China.

Washington should also launch a series of discussions with its allies to determine what new institutional mechanisms, commitments, and structures are needed to defend against economic attacks, not just military ones.

We should ensure the ability to take joint reciprocal action against Beijing in the economic realm, particularly to defend smaller countries. China engages in economic coercion because it is effective and relatively risk-free. But if instead like-minded countries responded together when one was attacked economically, this would go a long way in discouraging Beijing from employing such tactics.

Using all the tools of power

A critical first step is mapping dependencies on China and investigating how to limit over-dependence that open democracies to unacceptable economic vulnerability. As in the military realm, we need to enhance our resiliency against attack by avoiding over-dependence on any single import, export, or supply chain decency. This is a task that the so-called D10 (G7 plus Australia, India, and South Korea) should take up early next year.

The good news is a collective response to Chinese economic coercion will be more feasible under a Biden administration. President-elect Joe Biden and his senior advisers have articulated a preference for multilateral responses to Chinese aggression.

And while President Donald Trump relied mainly on military moves to warn and punish Beijing, Biden’s team prefers to make use of all tools of power. For these reasons, there has even been talk of rejuvenating past efforts like TPP. US allies and partners are also likely to see Biden as more reliable, making them more willing to undertake the risky venture of joining forces against Beijing.

The United States, Australia, and other allies and partners tried to welcome China into the international community. This was the right move. It has been good economically for many advanced economies, including Australia and the United States. But there is a flip side to every coin.

Australia has become too vulnerable to the whims of Beijing. And the US has few options to protect against such economic pressure. The incoming Biden administration needs to fundamentally rethink the nature of alliances so that countries like Australia have a third option the next time Beijing forces a choice between freedom and prosperity.
