In 2025, China was once again among the most important foreign investors across Southeast Asia, but nowhere was the shift more visible than in Việt Nam. The country has become a focal point for Chinese capital not only because of geography and labor costs but also because the global map of trade, tariffs, and industrial relocation has changed.

What began as a tactical move to diversify supply chains has become a structural reordering of Việt Nam’s economy. By the first nine months of 2025, Chinese FDI (Foreign Direct Investment) was the second largest source of newly licensed foreign projects in Việt Nam, according to Việt Nam’s National Statistics Office.

This information was from Chen Heyi , an independent analyst who studies China’s economic and political engagement in Southeast Asia. The Vietnamese Magazine spoke with her as our regional analyst covering China–Southeast Asia relations.

Chen further stated that realized FDI reached $18.8 billion over the same period, the highest nine-month figure in five years, while full-year disbursement later climbed to an estimated $27.62 billion.

At the same time, newly registered foreign capital for the year reached $38.42 billion. The message is clear: Việt Nam is not merely receiving more foreign investment; it is receiving more Chinese-linked investment at the center of its manufacturing model.

That shift matters because Chinese capital is arriving in Việt Nam through different channels and with different intentions.

Some investors are chasing industrial relocation. Others are building strategic infrastructure. Others are entering Việt Nam as globally scaled firms trying to localize production, win market share, and secure regional supply chains.

The result is not one China strategy in Việt Nam, but several overlapping ones, commercial, geopolitical, and industrial, all at once.

China, Plus One Effect

Chen Heyi, in our interview, states that history is essential to understanding the relationship. She points to the long China-Việt Nam relationship but also to the trauma of the China-Vietnam War of 1979, which left a deep political and social imprint.

For years, China was a sensitive subject in Việt Nam, and the relationship never returned to a purely sentimental or symbolic footing. That legacy still shapes how Hà Nội manages Chinese investment today: with openness, but also with caution.

The timing of the current investment surge is deliberate. According to Chen’s analysis, the turning point came as the U.S.-China trade conflict intensified and China's plus-one strategies spread through global supply chains. Việt Nam was one of the biggest beneficiaries.

Việt Nam’s labor costs, industrial zones, export capacity, and trade agreements made it a natural destination for firms seeking to preserve access to Western markets while reducing exposure to tariffs and disruption in mainland China.

Sources have repeatedly shown that Vietnamese exports to the United States have surged in parallel with rising imports from China, a pattern that underscores Việt Nam’s role as both a production base and a processing hub within regional supply chains.

The structure of this Chinese investment wave is what makes Việt Nam especially important. State-owned enterprises are visible in the large, strategic layers of the economy: energy, infrastructure, logistics, and other capital-heavy sectors where scale matters more than immediate returns.

Privately owned enterprises are the most agile actors, especially in labor-intensive manufacturing and export assembly. And increasingly, Chinese firms are entering Việt Nam as more sophisticated multinational enterprises, pursuing not only relocation but also brand building, localization, and regional expansion.

In Việt Nam, those differences are shaping the economy the country is becoming.

Supply Chains, Dependency, and the Transshipment Risk

State-linked capital tends to arrive with a longer time horizon and deeper political meaning. In Việt Nam, that makes it particularly relevant to infrastructure and energy, sectors that require heavy upfront spending and close ties to the state. Hà Nội needs new power generation, logistics, transportation links, and industrial capacity.

Chinese state-backed firms are well-positioned to fill some of those gaps. But their presence also creates strategic questions. Infrastructure becomes more than just infrastructure when geopolitical competition catches up with it. It becomes leverage, dependence, and sometimes vulnerability.

Private Chinese firms, by contrast, are the most responsive to market conditions. They do not need the same degree of political symbolism. They follow costs, tariffs, and supply chain risks. Việt Nam is attractive to them because it offers a relatively young workforce, a strong export platform, and proximity to China’s own manufacturing ecosystems.

Many of these firms are not trying to replace China; they are trying to extend it. Their factories in northern and central Việt Nam often import components from China, assemble products in Việt Nam, and then export them onward to the U.S. or Europe.

Reuters reported in September 2025 that Việt Nam continued to rely heavily on Chinese materials and equipment for manufacturing, with imports from China up 27% in the first eight months of the year to $117.93 billion.

That dependence is the core contradiction in the current boom. Việt Nam is benefiting from Chinese capital precisely because it is becoming more embedded in Chinese supply chains. Yet the deeper that embedding becomes, the more exposed Việt Nam is to external scrutiny, especially from Washington.

This is where the transshipment issue becomes crucial. Speaking with The Vietnamese Magazine, Chen Heyi warns that some Chinese goods pass through Việt Nam, get relabeled as Vietnamese, and then get re-exported to third markets.

Trade authorities around the world are increasingly penalizing this practice, known as transshipment. Reuters reported in July 2025 that Việt Nam was preparing stricter penalties for illegal transshipment and had focused inspections on Chinese products as part of its effort to comply with commitments made to Washington.

The U.S. had already cut threatened tariffs on imports from Việt Nam to 20%, but goods deemed illegally transshipped could still face a 40% levy.

That pressure matters because Việt Nam’s trade model has become increasingly bilateral in an asymmetric way: exports to the United States rise, while imports from China rise alongside them.

Reuters also stated that in 2025 Việt Nam’s exports to the U.S. remained strong, but that its imports from China also climbed sharply, reflecting the country’s role as a manufacturing platform dependent on Chinese intermediate goods.

In other words, Việt Nam is not simply exporting more; it is increasingly processing and rerouting more. That model can be profitable, but it is also fragile.

Between Opportunity and Strategic Constraint

Chen also highlights a broader political reality: the economic relationship can improve even when the political relationship remains uneasy. That is precisely what has happened in Việt Nam.

The South China Sea dispute remains unresolved. Public suspicion of China has never disappeared. Yet Chinese firms keep expanding because the economics still work.

In the same interview with The Vietnamese Magazine, Chen argues necessity—not trust—has pulled the two countries closer together. The global system of tariffs, supply chain hedging, and industrial relocation has made cooperation more attractive than separation.

This is why the Chinese presence in Việt Nam should not be read only through the lens of cheap labor. Labor costs were the first attraction, but they are no longer the main story.

Today, the attraction is also about industrial ecosystem depth, access to regional markets, and the ability to use Việt Nam as a hedge against trade uncertainty.

In December 2025, Reuters also documented that Chinese and Hong Kong firms pledged more than $6.7 billion in Việt Nam in the first eleven months of the year, making them the country’s largest investors in that period. At one industrial park in northern Việt Nam, Chinese manufacturers reportedly made up a quarter of tenants, up from 10% in 2019.

The composition of that investment is equally revealing. Chinese firms are not all coming for the same reasons. Some are building factories to serve foreign demand. Some are forming joint ventures with Vietnamese partners. Some are transferring technology.

In 2025, technology transfer deals were increasing, with several Chinese investors preparing to share technology with Vietnamese partners, a sign that parts of Chinese investment were moving beyond pure tariff arbitrage into deeper operational integration.

This suggests that Việt Nam is beginning to attract not only relocation capital, but also strategic industrial capital with longer horizons. That evolution presents both opportunities and risks for Việt Nam.

But the opportunity is obvious. Chinese investment can accelerate industrial upgrading, expand export capacity, deepen local supplier networks, and help finance the energy and logistics systems needed for a more advanced economy.

It can also support sectors such as electric vehicles, batteries, solar equipment, and electronics—industries that Việt Nam wants to climb into, not just assemble for others. Chinese firms already have strong experience in these sectors, and their arrival can help Việt Nam accelerate its manufacturing sophistication.

And the risk is equally obvious. If Chinese capital enters primarily as low-value assembly or as transshipment infrastructure, then Việt Nam may bear the downside and not the value.

It may absorb trade scrutiny, tariff exposure, and regulatory pressure, while the higher-margin parts of the value chain remain elsewhere. That is the central danger in relying too heavily on a model built around relocation rather than upgrading.

Việt Nam’s policy challenge, therefore, is not to reject Chinese investment. It is to shape it. Hà Nội needs to distinguish between capital that builds domestic capability and capital that merely exploits Việt Nam’s position in global trade routes.

It also needs to be alert to the political sensitivity of Chinese-backed infrastructure and technology projects. The country’s strategic balancing act will likely remain delicate: welcoming capital from China, while preventing overdependence on Chinese components, Chinese logistics, or Chinese market logic.

That balance is becoming harder because Việt Nam has become more successful. The more the country grows, the more attractive it is as a production base. The more attractive it becomes, the more it risks becoming a conduit in someone else’s supply chain.

That is why the current boom is not just an economic story. Chinese capital is neither “taking over” Việt Nam nor simply benefiting the country. It is negotiating a complex new phase of regional capitalism, one in which Chinese money is both an opportunity and a constraint.
