Beijing's ASEAN Gambit Stumbles as Washington Plays the Long Game
China's flashy infrastructure promises are losing steam while America's quiet tech partnerships reshape Southeast Asia's future
Singapore’s Marina Bay Sands casino was buzzing with more than just gamblers last Tuesday. Chinese Foreign Minister Wang Yi stormed out of a closed-door ASEAN meeting after Malaysian Prime Minister Anwar Ibrahim questioned Beijing’s latest South China Sea “clarifications” — the third such diplomatic flare-up in six months.
The incident, barely reported in Western media, captures a larger truth: China’s influence campaign in Southeast Asia is hitting serious turbulence just as the United States finds its footing after years of strategic drift.
I’ve watched this competition unfold from Yangon’s teahouses to Jakarta’s government towers for the past decade. What’s happening now isn’t just another round of great power rivalry. It’s a fundamental shift in how regional powers view their options between Washington and Beijing.
The Infrastructure Honeymoon is Over
China’s Belt and Road Initiative once seemed unstoppable in Southeast Asia. The promise was simple: Beijing would build the roads, ports, and railways that Western powers had neglected for generations.
That promise is cracking.
Thailand’s Eastern Economic Corridor rail project, trumpeted as BRI’s crown jewel when I first reported on it in 2019, remains 60% incomplete despite consuming $12.8 billion in Chinese loans. Local contractors tell me privately that Chinese project managers regularly clash with Thai environmental regulators, creating delays that have stretched the timeline from four years to at least eight.
Vietnam’s experience offers an even starker warning. The Cat Linh-Ha Dong metro line in Hanoi, built with $868 million in Chinese financing, finally opened in 2021 — five years behind schedule. When I rode it last month, half the stations showed visible water damage from Hanoi’s monsoons. Vietnamese officials now joke bitterly about “Chinese speed” meaning “twice as long as promised.”
But the real game-changer isn’t project delays. It’s debt.
Sri Lanka’s Hambantota Port disaster sent shockwaves through ASEAN capitals in 2022 when Colombo had to lease the facility to China for 99 years after defaulting on loans. Malaysia’s Najib Razak may be serving time for the 1MDB scandal, but his warnings about Chinese debt traps look prescient now that his successors are quietly renegotiating $40 billion in BRI commitments.
America’s Quiet Comeback
While China stumbled with concrete and steel, Washington took a different approach.
The Indo-Pacific Economic Framework, dismissed by critics as “NAFTA without the trade,” is proving more effective than anyone expected. Not because of grand infrastructure promises, but because American companies are solving immediate problems.
Take cybersecurity. When ransomware attacks paralyzed Indonesia’s national health system in January, it wasn’t Chinese tech giants that provided emergency assistance. Microsoft, working through the IPEF’s digital cooperation framework, had Jakarta’s systems running within 72 hours. Indonesian officials remember that speed.
I spent three days in Ho Chi Minh City last month watching American and Vietnamese engineers test 5G networks built with equipment from Nokia and Ericsson — notably not Huawei. Vietnam’s decision to exclude Chinese telecom gear from sensitive networks started as a security measure. Now it’s becoming an economic opportunity as Vietnamese firms partner with American companies on telecom exports to Cambodia and Laos.
The numbers tell the story. U.S. foreign direct investment in ASEAN reached $74.3 billion in 2025, up 23% from 2024. Chinese FDI, meanwhile, dropped 15% to $61.2 billion — the first time America has outinvested China in the region since 2016.
The Military Dimension
China’s military assertiveness in the South China Sea was supposed to demonstrate strength. Instead, it’s driving neighbors into America’s arms.
The Philippines offers the clearest example. When Chinese coast guard vessels used water cannons against Filipino supply ships near Second Thomas Shoal in December, Manila didn’t just protest. President Marcos Jr. announced three new U.S. military bases would open on Luzon island by mid-2026.
Even more telling: Indonesia, long the region’s champion of non-alignment, quietly signed a defense cooperation agreement with the Pentagon in February. The deal allows U.S. Navy vessels to refuel at Indonesian ports — something unthinkable during the Jokowi era.
Vietnam’s shift is subtler but equally significant. Hanoi hasn’t abandoned its “bamboo diplomacy” of bending with the wind, but the wind is clearly shifting. Vietnamese naval officers now train regularly with their American counterparts in what both sides carefully call “routine maritime cooperation.”
I could be wrong about this trajectory. China’s economic gravity remains immense, and Beijing has shown remarkable ability to course-correct when strategies fail.
But the pattern is clear across multiple countries and issue areas.
The Technology Battleground
The real contest isn’t over ports or military bases. It’s over who controls the digital infrastructure that will define Southeast Asia’s economic future.
China had a commanding early lead. Huawei and ZTE built the backbone networks that carry most of the region’s internet traffic. Alibaba’s cloud services dominate e-commerce platforms from Bangkok to Manila. TikTok shapes how 400 million Southeast Asians consume information.
That dominance is under assault, and not just from American government pressure.
Thailand’s central bank shocked markets in January by announcing that all financial institutions must transition away from Chinese-made core banking software by 2028. The official reason: “cybersecurity resilience.” The real reason, according to three bank executives I spoke with: growing concern about data sovereignty as U.S.-China tensions escalate.
Singapore, typically cautious about taking sides, has effectively created separate tech ecosystems for Chinese and Western companies. The city-state’s new digital governance framework requires companies to choose between operating in China-aligned networks or U.S.-aligned ones, but not both.
American tech companies are capitalizing on these openings with strategies tailored to regional concerns. Google’s decision to build three new data centers in Indonesia wasn’t just about market expansion. It was about offering Indonesian companies an alternative to storing sensitive data in Chinese-controlled servers.
Economic Realities vs. Security Concerns
Here’s where the competition gets complicated: China remains Southeast Asia’s largest trading partner, accounting for 22% of the region’s total trade in 2025. That economic relationship can’t be unwound quickly, even if governments wanted to.
But trade flows are shifting at the margins. Malaysia’s semiconductor exports to the United States increased 34% last year as American companies sought alternatives to Chinese suppliers. Vietnam’s textile industry is similarly benefiting as U.S. retailers diversify their supply chains.
The trend suggests not decoupling but what economists call “selective reshoring” — moving the most sensitive economic activities away from China while maintaining broader commercial relationships.
Indonesia exemplifies this approach. Jakarta continues importing Chinese consumer goods and sending raw materials to Chinese factories. But when President Prabowo chose partners for Indonesia’s new capital city in Borneo, American and Japanese firms won the most sensitive infrastructure contracts.
Regional Variations
Not every Southeast Asian country is following the same path away from Chinese influence.
Cambodia remains firmly in Beijing’s camp, with Prime Minister Hun Manet showing no signs of following his neighbors’ more independent policies. Chinese investment in Cambodia actually increased 12% in 2025, bucking the regional trend.
Laos, heavily indebted to Chinese lenders, has little choice but to maintain close ties with Beijing. The China-Laos railway, completed in 2021, has made the landlocked country even more dependent on Chinese trade routes.
Myanmar presents a special case. The military junta’s pariah status has left it almost entirely dependent on Chinese support, even as civilian resistance movements look to Western countries for backing.
But these outliers prove the rule rather than challenging it. The region’s major economies — Indonesia, Thailand, Vietnam, Philippines, Malaysia, Singapore — are all hedging away from excessive Chinese dependence.
The Taiwan Factor
Taiwan’s status looms over every aspect of U.S.-China competition in Southeast Asia, though officials rarely discuss it publicly.
ASEAN countries understand that any Chinese move against Taiwan would force them to choose sides in ways that economic competition does not. That prospect terrifies leaders who’ve built their foreign policies on strategic ambiguity.
The fear is driving preventive diplomacy. Singapore’s recent proposal for expanded ASEAN-China dialogue mechanisms isn’t just about managing South China Sea tensions. It’s about creating face-saving paths for Beijing to back down from Taiwan confrontation.
Whether those efforts will succeed depends partly on events beyond Southeast Asia’s control. But the region’s leaders are positioning themselves for multiple scenarios — another sign that exclusive alignment with either great power no longer seems wise.
Looking Ahead
Three factors will determine whether America’s recent gains in Southeast Asia prove durable or temporary.
First: economic performance. If U.S.-aligned supply chains and technology partnerships deliver sustained growth, they’ll be harder for China to counter. If they lead to slower development or higher costs, the appeal will fade quickly.
Second: Chinese adaptation. Beijing has shown remarkable strategic flexibility over the past four decades. If Chinese leaders recognize that heavy-handed tactics aren’t working and adjust accordingly, the competition could shift again.
Third: American staying power. Southeast Asian leaders remember the Obama administration’s “pivot to Asia” that never quite materialized. They remember Trump’s withdrawal from the Trans-Pacific Partnership. Consistency matters more than grand gestures in a region that thinks in decades, not election cycles.
What’s clear is that Southeast Asia’s strategic landscape has changed fundamentally over the past two years. The assumption that China’s rise was inevitable and irresistible no longer holds. Countries have options, and they’re increasingly willing to exercise them.
That doesn’t mean China is finished in Southeast Asia. Beijing’s economic and geographical advantages remain formidable. But the era of uncontested Chinese expansion in the region has ended.
For the United States, that creates opportunities that seemed impossible just five years ago. Whether American policymakers can capitalize on them without triggering the kind of great power confrontation that would devastate the region remains the biggest question of all.
The casino in Marina Bay where Wang Yi stormed out last week hosts high-stakes poker games every night. The U.S.-China competition for Southeast Asia increasingly resembles those games — careful calculation mixed with strategic bluffs, where reading your opponent matters as much as the cards in your hand.
Right now, America appears to be holding the better hand. But in geopolitics, as in poker, the game isn’t over until someone folds.
