On September 3, 2025, an extraordinary scene unfolded on the red carpet of Beijing’s Tiananmen Square. As the world’s cameras rolled, three of the globe’s most powerful and enigmatic leaders—China’s President Xi Jinping, Russia’s President Vladimir Putin, and North Korea’s Kim Jong Un—walked side by side toward a viewing platform for a massive military parade. Their conversation, caught by a hot mic and broadcast by Chinese state media, revealed an unexpectedly candid moment: the leaders were musing about the possibility of living to 150 years old, organ transplants, and even immortality.
The parade was more than just a display of military might. Ostensibly, it commemorated the 80th anniversary of Japan’s defeat in World War II, but with 26 international leaders present, it was also a symbolic show of Beijing’s global partnerships and a subtle challenge to the U.S.-led world order. For many in the West, the event signaled a new era of assertive diplomacy from China and its closest allies.
As Xi, Putin, and Kim led the delegation, their conversation drifted from pleasantries to the subject of longevity. Xi, 72, was heard telling his companions, “Now people in their 70s are still young.” Putin, also 72, responded with a line from a Tang dynasty poem, relayed by a translator: “Earlier, people rarely lived past 70, but these days at 70 years… still a child.” The conversation took a futuristic turn as Putin’s translator remarked, “In a few years, with the development of biotechnology, human organs can be constantly transplanted so that people can live younger and younger, and even become immortal.”
Xi, appearing both amused and thoughtful, added, “The prediction is that in this century humans may live to 150 years old.” The Russian translator relayed this to Putin, who later confirmed the exchange to reporters. “Modern means of healing, and medical means, all kinds of surgical means related to organ replacement, they allow humanity to hope that active life will continue not as it does today,” Putin explained, according to CNN. “The average age in different countries is different, but nevertheless, life expectancy will increase significantly.”
Kim Jong Un, at 41, was seen grinning at his older counterparts’ musings. It was his first multilateral diplomatic event alongside both Xi and Putin, and his presence sparked additional interest—especially as he appeared with his daughter, Kim Ju Ae, prompting speculation about succession plans in Pyongyang. North Korea’s leadership has passed from father to son for generations, and the public appearance of Kim’s daughter was widely interpreted as a signal about the regime’s future.
For Xi and Putin, the conversation about longevity carried a particular resonance. Both men have taken extraordinary steps to extend their time in power. Xi, who became president in 2013, abolished China’s presidential term limits in 2018 and was handed a third term in 2023, breaking with decades of political precedent. Under his leadership, the Chinese Communist Party has tightened its grip on society and politics, with no clear successor in sight. According to BBC, “Xi’s predecessors Jiang Zemin and Hu Jintao relinquished power after 10 years in office, but Xi has shown no intention of stepping down.”
Putin, meanwhile, has ruled Russia as either president or prime minister since 2000. In 2020, he pushed through constitutional changes allowing him to remain in power until 2036. He was re-elected in 2024, and, as NBC News points out, is now “the longest-serving Kremlin leader since Soviet dictator Josef Stalin.” Putin has a well-documented interest in longevity; Russian lawmakers even established an anti-aging research center in 2024, following his call for a national focus on health preservation.
The leaders’ musings on organ transplants and biotechnology were not entirely idle. Advances in medical science have indeed pushed the boundaries of human life expectancy, and both Russia and China have invested heavily in related research. But the topic is especially sensitive in China, where organ transplants have long been controversial. Rights groups allege that organs were harvested from executed prisoners, even after Beijing pledged to end the practice in 2014. China has also struggled with a severe shortage of donated organs, in part due to cultural taboos. In 2016, the World Health Organization convened a summit in Beijing to address ongoing skepticism about the country’s transplant system. As recently as 2023, the Chinese government introduced new regulations to tighten oversight and promote public awareness of organ donation, according to NBC News.
Despite these reforms, the black-market trade in organs remains a concern, and the government’s efforts to reassure the international community have met with only partial success. “China has historically had one of the lowest rates of organ donation with a long-standing black-market organ trade,” CBS News reported. These realities cast a shadow over the leaders’ optimistic talk of medical breakthroughs and immortality.
In Russia, the focus on longevity has become a political talking point. Putin’s government touts advances in anti-aging technologies as part of its broader strategy to project strength and stability. As he told reporters after the parade, “Modern means, both health improvement, and medical means, and even all kinds of surgical ones related to organ replacement, allow humanity to hope that active life will continue not as it does today.” He also referenced United Nations estimates that by 2050, the number of people over 60 would more than double the number of children under five, warning of the “social, political and economic consequences” such demographic shifts could entail.
Back in Beijing, the hot-mic moment drew little attention on Chinese social media, which is heavily censored. But internationally, the exchange has become a symbol of the ambitions—and anxieties—of a new generation of autocratic rulers. As Anton Sokolin of NK News observed, “North Korean leader Kim Jong Un cracked a smile after overhearing his older Russian and Chinese counterparts chat about living forever at Wednesday’s military parade in Beijing, a conversation that has made global headlines after being captured on a hot mic.”
For all the talk of biotechnology and immortality, the scene on Tiananmen Square was a reminder that power, like life itself, is fleeting. Yet for now, Xi, Putin, and Kim seem determined to defy both history and biology, holding fast to their thrones as they contemplate a future where even 150 years might not be enough.
