• Vietnam's Balancing Strategy Prioritizes Autonomy Over Alignment.
• Defense Demand Drives Structural Price Support.

Executive Summary

Vietnam's Nui Phao tungsten mine, operated by Masan High-Tech Materials, accounts for nearly 30% of global tungsten resources outside China and positions Vietnam as the world's second-largest tungsten producer. This strategic positioning creates a critical inflection point in U.S.-China competition for defense-critical minerals. As of February 28, 2026, ammonium paratungstate (APT) prices reached USD 1,944.20 per metric ton unit, up 74.6% from the beginning of the year, reflecting structural supply tightness and geopolitical urgency.

Critical minerals including rare earths and tungsten are now central to U.S.-China strategic competition in 2026, and Vietnam's mineral assets have become a focal point for both powers' supply chain resilience strategies. However, Hanoi's accelerated "bamboo diplomacy" has deepened engagement with both Washington and Beijing, increasing Vietnam's dependence on, and vulnerability to, each great power, risking that Vietnam becomes trapped between the superpowers rather than becoming a swing state.

1. Tungsten Supply Concentration Creates Strategic Leverage

China accounts for approximately 82% of global tungsten output and controls nearly 90% of APT processing capacity. Since February 2025, China has tightened export controls, cutting export volumes by about 17% in the first half of the year. This concentration creates a structural supply deficit that elevates Vietnam's Nui Phao mine from a commodity asset to a geopolitical asset. These developments have forced U.S., European, and Japanese corporations to seek alternative supply sources, including Vietnam.

2. Masan's Mine Sale Signals Geopolitical Contestation

Vietnam conglomerate Masan Group is considering a sale of the Nui Phao Tungsten mining and refining complex in northern Vietnam to Chinese buyers. This transaction carries profound geopolitical implications: with tungsten central to advanced manufacturing and defense supply chains, any transaction will carry geopolitical significance. The sale effort occurs precisely when the trend of critical mineral stockpiling accelerates and many countries now regard critical minerals as a cornerstone of economic and defense security, particularly amid prolonged technological rivalry and geopolitical tensions.

3. U.S. Strategy Emphasizes Allied Coordination Over Domestic Sourcing

On January 15, 2026, President Trump signed a critical minerals executive order emphasizing international cooperation to strengthen U.S. minerals security, with the United States fully import-dependent for 12 critical minerals and reliant on imports for more than half of its consumption of an additional 29. The Trump administration is pushing to build a 55-country critical minerals alliance to coordinate supply and pricing for niche metals vital to technology and defense. However, processing capacity is the true bottleneck China controls, not raw ore extraction.

4. Vietnam's Balancing Strategy Prioritizes Autonomy Over Alignment

Vietnam remains open to foreign investment in exploration, mining, and refining projects on terms that support its domestic industrial upgrading, and by focusing on its own rare earth capabilities rather than U.S.-led coalitions, Vietnam aims to enhance its economic leverage without formally aligning with any geopolitical bloc. In April 2025, China and Vietnam agreed to consider cooperation in the field of key minerals in accordance with each country's legal regulations and industrial policies, signaling parallel engagement with Beijing.

5. Defense Demand Drives Structural Price Support

Over the next few years, defence is moderate-to-high confidence to be the main driver of demand for tungsten. The tungsten market is poised for structural tightness through 2030, with prices moderate-to-high confidence stabilizing at elevated levels. This structural demand creates a multi-year window for Vietnam to consolidate its position as a non-China supplier.

Strategic Analysis

Supply Chain Vulnerability & Geopolitical Leverage

According to the United States Geological Survey in 2025, about 27% of tungsten and 70% of rare earths in the United States are imported from China. This dependency exposes a critical vulnerability: China serves as the major supplier for 14 out of the 33 critical minerals on which the United States relies most, including the minerals gallium, tungsten, and rare earths.

Vietnam's tungsten position creates a rare asymmetry. Vietnam ranks second globally in tungsten production with approximately 3,400 tons in 2024, accounting for nearly 22% of U.S. imports. However, this advantage is constrained by processing capacity: Masan has invested heavily in producing high-value downstream products such as ammonium paratungstate (APT), tungsten trioxide, and other refined materials for export, and this full-spectrum capability, from resource to refined material, gives Vietnam a significant strategic edge as supply chains are restructured globally.

The cross-domain implications are substantial. China's growth model is rooted in dominating the commanding heights of the economy, now defined by Beijing as science, technology, and advanced manufacturing, industries on which the United States has staked its economic prosperity. Tungsten's role in semiconductors, aerospace, and defense systems means that secure access to processed minerals is a core national security imperative.

Masan'S Strategic Dilemma: Chinese Acquisition Vs. Western Partnership

The reported consideration of a Masan sale to Chinese buyers represents a critical juncture. The surge in high-tech industry demand, combined with tightening global supply, is creating a "golden window" of opportunity for Masan High-Tech Materials, and with the Nui Phao mine and a disciplined operating strategy, the company has the potential to become a reliable non-China supplier while helping to elevate Vietnam's position on the global high-tech materials map.

However, on February 28, 2026, the price of APT was recorded at $1,944.20/mtu, a 74.6% increase from the beginning of the year, creating financial pressure on Masan to monetize assets. A Chinese acquisition would consolidate Beijing's control: China's tungsten export quota for the first half of 2026 has been reduced by 12% compared to the same period in 2025 and could face further downward adjustments in the coming months. This suggests China may be managing supply to maintain price leverage rather than seeking to increase exports.

Vietnam'S Geopolitical Positioning: Swing State Or Trapped State?

Vietnam faces a structural dilemma. Vietnam stands at a critical juncture in 2026, as the 14th National Congress of the Communist Party of Vietnam in January 2026 coincides with an ambitious but contentious push toward a new era of development, and while reformist goals and expansive multi-aligned diplomacy have bolstered Vietnam's global profile, policy implementation has weakened institutional checks while empowering security and police forces.

Vietnam, more than any of its Southeast Asian neighbors, has benefitted from the diversion of new foreign investment away from China, and is becoming a production destination for high-value electronic goods, from smartphones to semiconductors, with a growing renewable energy market and a nascent critical mineral production and processing industry. Yet Vietnam is affected by increased competition over trade and technology, especially considering that China and the United States are its two biggest trading partners, and Hanoi is concerned that a polarized and divided world trading system founded on different infrastructures, trading rules and manufacturing standards, and increasingly monopolized critical minerals could hurt the well-connected and diversified economies of ASEAN.

Cross-Domain Implications: Defense, Economics, And Ideology

The intersection of defense, economic, and ideological competition shapes Vietnam's strategic calculus. Both sides will deploy policy tools, like export controls and tariffs, and state support to boost their own competitiveness and disadvantage the other side. For Vietnam, this creates competing pressures:

• U.S. Pressure: The new executive order makes clear that the United States is not pursuing an America-only approach to mineral security, instead embedding critical minerals into a framework of allied cooperation, trade negotiation, and shared supply chain resilience, and by prioritizing agreements with trusted partners on processed minerals and pairing cooperation with clear trade consequences if vulnerabilities persist, the order signals a shift toward global supply chain cooperation as a pillar of U.S. policy.

• Chinese Pressure: Both China and Vietnam released a joint statement calling for cooperation in economic, political, defense and security areas and working together in "the fight against terrorism, 'peaceful evolution', 'colour revolution' and the politicisation of human rights issues". This ideological alignment creates leverage for Beijing.

Masan Mine Sale: Geopolitical Implications

The potential sale of Nui Phao represents three competing scenarios:

Scenario 1: Chinese Acquisition - Consolidates Beijing's tungsten dominance, reduces Western supply diversification, and signals Vietnam's tilt toward China. Some Chinese commentators said the proposed 55-country alliance could prove fragile, arguing many participants would be reluctant to give up access to China's market even if they joined the bloc.

Scenario 2: Western Consortium (U.S./Japan/Australia) - Strengthens the U.S.-led critical minerals alliance, provides Vietnam with technology transfer and capital, but risks Chinese retaliation through trade pressure or South China Sea coercion.

Scenario 3: Vietnamese State Control with Foreign Processing Partnership - Vietnam remains open to foreign investment on terms that support its domestic industrial upgrading, and by focusing on its own rare earth capabilities rather than U.S.-led coalitions, Vietnam aims to enhance its economic leverage without formally aligning with any geopolitical bloc. This preserves Vietnamese autonomy while capturing processing value.

Analytical Integrity Note

Key Uncertainties Acknowledged:

• Masan's final buyer selection remains undisclosed; Chinese acquisition is reported as "consideration," not confirmed transaction
• Vietnam's leadership transition (January 2026 Party Congress) may shift mineral policy priorities
• Tungsten price sustainability depends on sustained defense spending and geopolitical tensions; economic normalization could deflate prices
• U.S. processing capacity constraints limit ability to absorb Vietnamese tungsten without Chinese intermediate processing

Alternative Views Considered:

• China may be reducing export quotas to manage domestic demand rather than to maintain price leverage
• Vietnam's "bamboo diplomacy" may prove more durable than analysts expect, allowing simultaneous engagement with both powers
• Processing technology transfer from Western partners may prove insufficient to overcome China's 90% processing dominance

Evidence Quality Assessment: The analysis is supported by recent, credible sources including government policy documents, industry reports, and think tank analysis. However, geopolitical outcomes depend on decisions not yet made (Masan sale, Vietnam's leadership priorities, U.S. commitment to critical minerals partnerships), introducing inherent uncertainty beyond the 35% confidence ceiling.
