US brain drain handing the global talent war to China
The US-China rivalry is no longer just a clash of tariffs, navies and diplomatic showdowns. A quieter, subtler front has emerged – one that is nonetheless reshaping the global order and deciding future winners and losers. It's a contest for people, specifically the scientists, engineers and academic pioneers who will shape the future.
In this emerging struggle, talent is the new oil and the pipelines are shifting as the once-unidirectional flow of talent toward the United States is reversing, redirecting careers, rebalancing innovation and redrawing the map of global power and influence.
Thousands of highly skilled professionals, especially those of Chinese descent, are leaving American institutions for new opportunities in China and elsewhere. This is more than a reversal; it is a redistribution of global brainpower, one that is reshaping research ecosystems and tilting discernibly the balance of global innovation.
Between 2010 and 2021, nearly 20,000 Chinese-born scientists left the United States, a trend that accelerated after 2018. These are not second-string researchers: they include figures like neuroscientist Yan Ning, who left Princeton to lead the Shenzhen Medical Academy, and Gang Chen, a top MIT engineer who returned to Tsinghua University after being cleared of espionage-related charges.
Increasingly under Trump, restrictive visa policies, geopolitics and racialized suspicion are repelling rather than attracting top talent. The previous Trump administration's China Initiative may be over, but its chilling effect remains.
Chinese and other Asian scientists worry about surveillance, unjust scrutiny or even prosecution. Simultaneously, shrinking research budgets and unstable funding make the US less attractive.
Added to that is a cultural atmosphere strained by rising anti-Asian sentiment. For many scientists, it is not just about funding, it is about a sense of belonging, and increasingly, they feel like they don't.
Personal reasons matter too: proximity to family, cultural affinity and a desire to build something at home are strong motivators for many. The choice is not always ideological; sometimes, it is just practical.
Meanwhile, countries like China are actively luring top talent. Programs like the Thousand Talents Plan offer not only top-tier salaries and research budgets, but also housing, leadership roles and prestige.
Institutions like Westlake University and the Shenzhen Medical Academy promise autonomy and world-class facilities. For many, returning to China is no longer a step down but rather a step up.
China's talent recruitment is strategic and political. Scientists are welcomed back with fanfare, but also with expectations. Loyalty to the Chinese Communist Party matters. Returnees are integrated into networks that blend scientific leadership with ideological alignment.
Yet even within these constraints, China offers room to lead. The government knows innovation cannot be fully micromanaged, so it invests heavily in reducing red tape and offering clear career trajectories. The result is a paradox: a system that demands control but depends on creativity.
Returnees also serve as powerful symbols. Chinese media portray their return as validation of China's rise and the West's decline. These narratives bolster nationalism and legitimize the regime. But the government knows this soft power cuts both ways: Disillusioned returnees could become critics, so integration and respect are key.
This moment raises an important question: Is China reaching a true inflection point in its ascent as a scientific superpower? For some, the symbolism is striking. Mao Zedong once declared the rise of the Chinese people on the world stage. Today, the return of world-class scientists to China could be seen as a realization of that prophecy – not through revolution but rather through research.
China's growing ecosystem of labs, research parks and universities is producing world-class science. Its top research institutions are climbing global rankings. Its researchers are making breakthroughs in quantum computing, artificial intelligence and biomedicine. If this trajectory holds, China may soon rival or surpass the United States in the highest tiers of innovation and technology.
But the path is not guaranteed. Real leadership in science requires openness, trust and intellectual freedom – qualities that sit uneasily with China's political leadership. Whether China's scientific rise is sustainable will depend on how the Communist Party manages these tensions.
Is this the beginning of a new Chinese scientific century, or a premature peak? The answer lies in how China balances its national ambitions with the global ethos and norms of science.
For the United States, the loss of top researchers is a clear threat to its innovation edge, jeopardizing future breakthroughs in AI, biotech and clean tech. It also weakens American soft power. The American university used to be the global gold standard, but that aura is now fading.
China, on the other hand, is reaping real benefits, with returnees driving progress in key innovation sectors. Chinese universities, meanwhile, are climbing in global rankings. It's all giving Beijing cause to tout these successes as proof of its system's superiority.
Globally, talent flows are becoming more fluid. Brain circulation, not just brain drain, is creating new innovation hubs in places like Singapore, Germany and the UAE. These countries are benefiting from researchers disillusioned with both Washington and Beijing. The science world is thus becoming decentralized and more competitive.
But also more fragmented. As US-China collaboration collapses, Europe and others are increasingly being forced to pick geopolitical sides. The science world is slowly but surely breaking into competitive blocs.
In response, the US has gone on the defensive. National security policies like Project 2025 and export controls aim to wall off critical technologies. But this fortress mentality could backfire if it alienates more and more international talent. If it goes too far, the US could easily find itself isolated in the global innovation race.
Some US universities and tech leaders are pushing back, calling for visa reform and more support for international students and scholars. But without federal leadership and a clear vision, the drift and alienation of talent is set to continue under Trump.
China, meanwhile, is doubling down on luring talent home. It sees returnees as key players in its 'moonshot' initiatives, ranging from quantum computing to green tech. The challenge for Beijing is maintaining enough openness to keep innovation alive while ensuring loyalty.
Other nations are also seizing the moment. Canada, Australia and parts of Europe are streamlining immigration for scientists. The future may not be bipolar but multipolar, with a mosaic of innovation centers replacing the old US-centric model.
The United States must act decisively. Immigration reform is essential, including green cards for STEM graduates, simplified visa processes and a clear welcome message. Combatting anti-Asian racism in academic and professional spaces is also critical.
Beyond that, the US must recommit to public investment in science, not just for military goals but for shared human progress. Building global collaborations, not tearing them down, will help retain trust and talent.
China must also tread carefully. Over-politicizing science risks smothering the innovation it seeks and craves. It needs to protect intellectual freedom, promote interdisciplinary research and allow greater institutional autonomy.
Other countries will likely continue cultivating environments where scientists can thrive regardless of their national origin. Science is inherently global, and countries that embrace this will punch above their weight in the coming decades.
The world is witnessing a quiet revolution as global brain drain morphs into brain circulation. The old assumption that the West is the final stop for talent no longer holds.
China is rewriting the rules and the US is at risk of writing itself out of the game. The winners will be those who recognize that global talent seeks trust, opportunity and, just as importantly, respect.
In the new world of global competition, it's not just about who builds the fastest chip or finds the next vaccine. It's about who people trust to build a future they're willing to work toward.

Tackle discrimination against Pakistanis in Hong Kong at the roots
Feel strongly about these letters, or any other aspects of the news? Share your views by emailing us your Letter to the Editor at letters@ or filling in this Google form . Submissions should not exceed 400 words, and must include your full name and address, plus a phone number for verification The core strength of a global city like Hong Kong lies in multiculturalism. However, the challenges faced by the Pakistani community, highlighted at a forum on May 27, are stark and deeply concerning. Higher unemployment rates, lower-than-average income levels and the highest poverty rate in the city reveal a profound crisis of systemic inequality. While inadequate Chinese language skills and lower educational attainment are often cited, the root cause is deeply entrenched systemic discrimination. From educational segregation and workplace exclusion to social marginalisation, these structural issues demand urgent attention from both government and society to achieve genuine inclusion. Systemic deficiencies in education are particularly pressing. The Audit Commission has highlighted that many Chinese language teachers lack the training needed to educate second-language learners , leading to a persistent lag in Chinese proficiency among students from diverse ethnic backgrounds. Furthermore, schools continue to be segregated, with close to 40 per cent of primary pupils from diverse ethnicities attending schools where over 60 per cent of the student body are from these backgrounds – a concentration that may hinder integration and Chinese language acquisition. The authorities must mandate teacher training, establish a unified curriculum and incentivise the desegregation of schools; otherwise, educational equality will remain an empty promise.

Hong Kong to keep expanding land bank, but not to offset deficit: Paul Chan
Hong Kong will press on with building up its land bank but adopt a cautious stance on selling the sites, the finance chief has said, rejecting the notion the government is rushing to find and sell parcels to offset the budget deficit Financial Secretary Paul Chan Mo-po also said in a recent interview that the government would address plans to build artificial islands off Lantau waters 'later', despite calls from developers to halt the project immediately. 'We will not stop [creating land] because of property prices and the market; we will keep producing land,' he said. 'Having created the land, we don't need to sell it immediately. It can form part of our land bank. 'The message is that the government has land. But how and when to sell it, we will act according to market conditions. At the moment, it is of utmost importance to manage expectations and confidence … we will put [the land] on the market cautiously. 'Some have suspected that the government hopes to sell land to cover its budget deficit. That's not the case.' Chan revealed a deficit of HK$87.2 billion (US$11.1 billion) in his budget in February and outlined a series of measures to cut public expenditure and raise revenue to address the fiscal challenge.

Iran vows payback as Trump hints at regime change
Iran on Sunday threatened US bases in the Middle East after massive air strikes that Washington said had destroyed Tehran's nuclear programme, though some officials cautioned that the extent of damage was concern focused on fears that the unprecedented US attacks would deepen conflict in the volatile region after Israel launched a bombing campaign against Iran earlier this Akbar Velayati, an adviser to Iran's supreme leader Ayatollah Ali Khamenei, said bases used by US forces could be attacked in retaliation."Any country in the region or elsewhere that is used by American forces to strike Iran will be considered a legitimate target for our armed forces," he said in a message carried by the official IRNA news agency."America has attacked the heart of the Islamic world and must await irreparable consequences."US President Donald Trump urged Iran to end the conflict after he launched surprise strikes on a key underground uranium enrichment site at Fordo, along with nuclear facilities in Isfahan and Natanz."We had a spectacular military success yesterday, taking the 'bomb' right out of their hands (and they would use it if they could!)" he said on social while the US president did not directly advocate regime change in the Islamic republic, he openly played with the idea -- even after his aides stressed that was not a goal of American intervention."It's not politically correct to use the term, 'Regime Change,' Trump posted on his Truth Social platform. "But if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn't there be a Regime change??? MIGA!!!"RTHK's Washington correspondent, Simon Marks, said Trump's remarks were certain to spark more speculation about his steps."But all of this... raises a massive question, which is, to what extent is Donald Trump committed to moving forward, possibly with more military action or committed to trying to foment some kind of change on the ground in Tehran?" He told RTHK's Hong Kong Today programme "Certainly, that's what (Israeli) Prime Minister Benjamin Netanyahu has been trying to do from Israel over the course of the last week. But the Americans have been holding back from that. Now, tonight, perhaps Donald Trump is flirting with the idea of adopting that position."Netanyahu, meanwhile, said his country's military strikes will "finish" once the stated objectives of destroying Iran's nuclear and missile capabilities have been achieved."We are very, very close to completing them," he told Iran's leaders struck defiant tones, President Masoud Pezeshkian also vowed that the United States would "receive a response" to the Khamenei adviser, Ali Shamkhani, said in a post on X that "even if nuclear sites are destroyed, game isn't over, enriched materials, indigenous knowledge, political will remain."Rafael Grossi, director of the International Atomic Energy Agency (IAEA), told an emergency meeting of the UN Security Council that craters were visible at the Fordo facility, but no one had been able to assess the underground added that attacks on nuclear facilities could cause radiation leaks, but the IAEA had not detected any.
