Kishore Mahbubani, the former president of the UN Security Council and a veteran Singapore diplomat, has declared that attempts to halt China's economic and geopolitical ascent are futile. His stark assessment: China "can no longer be stopped."
This warning arrives in May 2026 as Beijing's economy grows at 5% annually and its defense budget swells to $281 billion. For Thailand residents, investors, and policymakers, the implications are profound. The region's old order is visibly unraveling, and how Thailand navigates what comes next could reshape the nation's economy and security for decades.
Mahbubani argues that Washington has failed to devise a coherent strategy for managing what he calls the "biggest driver of history" for the next three to four decades. His assessment raises urgent questions: how should residents and investors position themselves in a region where American influence is receding and Chinese power is expanding?
Why This Matters
• Economic realignment: China's pivot toward BRICS and the Global South means direct trade corridors and investment flows into Southeast Asia, including Thailand.
• Military modernization: A 7% hike in China's defense spending, focused on AI and counter-hypersonic tech, reshapes the security calculus along the First Island Chain—waters Thailand relies on for trade.
• US rebalancing: Washington's 2026 National Defense Strategy prioritizes homeland defense and burden-sharing, signaling potential reduced US presence in Southeast Asia unless allies contribute more.
• Diplomatic hedging: Thailand's longstanding policy of strategic neutrality now faces its most consequential test since the Cold War.
The Mahbubani Thesis: Geopolitics as Iron Law
Mahbubani, speaking at the 12th China and Globalization Forum in Beijing and later on Channel 4 News in April 2026, framed the US-China rivalry not as a clash of personalities but as an inevitable collision dictated by the logic of geopolitics. He invoked what he terms the iron laws of power: an emerging giant will inevitably challenge the incumbent hegemon.
Yet he also noted a startling reversal: the US, historically the champion of multilateral institutions, now acts unilaterally under the second Trump administration, while China positions itself as a defender of globalization and multilateralism.
At the China Conference hosted by the American Chamber of Commerce in Hong Kong, Mahbubani projected that the economic gap between the two powers could widen to $11 trillion by decade's end—in China's favor if current trajectories hold. He stressed that anyone doubting American economic resilience "ought to have his head examined," but cautioned equally against underestimating China, whose rise he describes as "the single largest transformation in world history."
His prescription? Both powers must step back and embrace wisdom and cooperation, particularly as geopolitical crises—such as ongoing tensions in the Strait of Hormuz—paradoxically create pressure for stabilization.
China's 2026 Reality: Growth, Guns, and Global Reach
The numbers behind Mahbubani's thesis are stark. China's economy expanded by 5% in Q1 2026, propelled by exports in AI, robotics, electric vehicles, and renewable energy—sectors central to its 15th Five-Year Plan. Analysts now forecast China could overtake the US economy by 2036, a timeline shorter than previous estimates.
Beijing has also diversified trade flows, reducing reliance on American markets and deepening partnerships with BRICS and Global South nations—a shift with immediate implications for Thailand, which sits at the crossroads of these new corridors.
Military expansion: The People's Liberation Army received a $281 billion budget in 2026, a 7% increase that outpaces official GDP growth. Investments flow into quantum sensing, AI-driven warfare, and counter-hypersonic systems, all focused on the PLA's 2027 centenary modernization goal. Reunification with Taiwan remains the primary strategic objective, with experts warning of heightened conflict risk. The South China Sea—through which Thailand's shipping lanes pass—continues its steady militarization.
Diplomatically, Beijing projects itself as a rational and respectful partner, especially to the Global South. High-level summits between Presidents Trump and Xi in late 2025 and May 2026 aimed to establish a "constructive relationship of strategic stability," yielding agreements on trade, financial stability, and food security, even as fault lines persist over AI competition, critical minerals, and Taiwan's status.
Washington's Pivot: Defense, Deterrence, and Delegation
The 2026 US National Defense Strategy reveals a fundamental reordering of priorities. Homeland defense—border security, narco-terrorism, nuclear and cyber modernization—now tops the agenda. The Indo-Pacific follows, but with a doctrine of deterrence by denial rather than forward dominance.
Washington wants allies, including those in Southeast Asia, to shoulder more of their own security costs, freeing US forces to rebalance toward North America and the Pacific.
For Thailand, this matters acutely. The strategy document calls for increased burden-sharing and accountability from partners, signaling that the era of guaranteed American security guarantees may be ending. Taiwan received less explicit mention in the NDS, raising concerns in Taipei—and among observers in Bangkok—that the US may view the island primarily as an economic rather than existential issue.
Some analysts argue the Trump administration has introduced a temporary pause in strategic competition, pursuing transactional economic deals over long-term strategic containment. Critics warn this could allow China to further undermine US influence in Asia, a development that would leave Thailand navigating a region where Beijing's gravitational pull is stronger than ever.
What This Means for Thai Residents and Investors
Thailand's strategic autonomy—its decades-long practice of balancing relations with major powers—now faces unprecedented complexity.
Belt and Road opportunities: Beijing's focus on infrastructure, connectivity, and financing offers tangible benefits. New rail links, port upgrades, and trade agreements could accelerate Thailand's industrial modernization. A Thai manufacturing firm supplying auto parts to US markets could face new export restrictions on advanced chips and sensors by Q3 2026, forcing diversification toward Asian buyers. Bangkok's Laem Chabang port, which handles 8.1 million TEUs annually, would see immediate disruption if Taiwan Strait tensions escalated—insurance premiums for container shipping jumped 40% during the 2025 South China Sea incident.
Supply chain shifts: China's pivot toward high-tech industries and diversified supply chains presents both opportunity and threat. Companies positioned to supply AI components, renewable energy parts, or electric vehicle batteries could benefit from Beijing's 15th Five-Year Plan. Conversely, those reliant on the US market may face regulatory headwinds as Washington tightens export controls.
Security concerns: China's 7% defense budget increase and continued militarization of the South China Sea directly affect Thailand's maritime trade routes, through which the majority of the nation's imports and exports flow. A conflict over Taiwan would disrupt these vital arteries, sending insurance premiums soaring and forcing Thai logistics firms to reroute shipments at significant cost.
Diplomatically, Thailand must calibrate its approach to ASEAN centrality, the bloc's preferred strategy for navigating US-China tensions. ASEAN's emphasis on unity, resilience, and industrialization aligns with Bangkok's interests, but member states express growing concern about China's expanding political influence. Thailand's challenge is to maximize economic engagement with Beijing while preserving freedom of maneuver in a multipolar landscape.
Alternatives to Containment: The Search for Middle Ground
Mahbubani's assertion that China cannot be stopped does not imply a zero-sum outcome. Several alternatives to outright containment are gaining traction among policymakers:
Managed competition or strategic stability emerged from the May 2026 Trump-Xi summit. The concept envisions both powers establishing pragmatic guardrails, improving communication channels, and cooperating on shared risks like AI governance, financial stability, and climate change, even as they compete fiercely in other domains.
De-risking and diversification, championed by the European Union, Japan, and India, focuses on reducing critical dependencies without full decoupling. For Thailand, this translates into diversifying supply chains, forging alternative partnerships, and strengthening domestic capabilities in strategic sectors.
Multipolarity, from Beijing's perspective, means an equal and orderly multipolar world where nations adhere to international rules. China presents itself as a great enabling power, focused on capacity creation rather than hegemony—a narrative that resonates in Bangkok, where infrastructure needs remain vast.
The Road Ahead
Mahbubani's warning in January 2026 that "the era of Western domination of world history is over" reflects a reality already visible in Thailand's markets, ports, and diplomatic calendars. The question for residents and investors is not whether China will rise—Mahbubani insists that trajectory is locked—but how Thailand will navigate a region where American influence is receding, Chinese power is expanding, and the rules of engagement remain unwritten.
The smart approach, backed by ASEAN's strategy, is to hedge, diversify, and build resilience. That means deepening economic ties with China while maintaining security cooperation with the US, investing in domestic industries that reduce dependence on any single power, and leveraging Thailand's geographic position as a logistics and manufacturing hub. The old certainties—a US-led order, predictable trade routes, stable alliances—are dissolving.
What replaces them will be shaped by decisions made in boardrooms, government offices, and factory floors across Thailand in the months and years ahead. Mahbubani's stark framing may discomfit those who prefer the familiar post-Cold War world. But for Thailand, a nation that has always thrived by reading geopolitical winds and adjusting its sails, the challenge is less about choosing sides than about building the institutional, economic, and strategic capacity to prosper in a world where power is shifting east—and where the rules are still being written.
