['The Third Vulnerability' After Oil and Semiconductors]

The dining tables of 1.4 billion people are stopping Xi Jinping's Taiwan clock. While the Chinese Communist Party (CCP) prides itself on securing rice and wheat, China is a country that must import 84% of its soybean consumption—which underpins meat, eggs, and cooking oil—from the opposite side of the globe. Oil can be weathered through reserves and detour routes, and semiconductors through domestic substitution, but soybeans cannot be hoarded long-term, easily replaced, or procured nearby. The moment artillery roars across the Pacific, even without a formal U.S. blockade, surging insurance premiums and retreating shipowners will sever the 45-day sea route, exhausting stockpiles within mere months. In a nation where memories of the Great Famine remain alive, empty dinner tables will simultaneously drain the regime's political legitimacy. An invasion of Taiwan is a gamble wagering not merely on Taiwan, but on the CCP regime itself, and the outcome will be decided at the dining table long before the battlefield. This is precisely the Chinese Communist Party’s fatal vulnerability.

Foreign Affairs, an American foreign policy magazine, published a commentary on the 2nd (local time) by Joel Wuthnow, a senior research fellow at the Center for the Study of Chinese Military Affairs at the U.S. National Defense University (NDU) Institute for National Strategic Studies (INSS), titled "The Limits of Chinese Self-Reliance: Why Food Insecurity Could Prevent a War Over Taiwan." As a military specialist studying the People's Liberation Army (PLA), he also served as the lead editor of Crossing the Strait, a study examining Taiwan invasion scenarios.

Foreign Affairs argued in this piece that while analyses assessing the likelihood of a Chinese attack on Taiwan have generally focused on three risks—military defeat, economic downturn, and cutoffs in imports of oil and advanced technologies—food must be added as an equally weighty variable. The core of this analysis lies in a military researcher finding the foundation of deterrence not in tanks or missiles, but in grain silos.

Beijing is well aware of this vulnerability. In his report to the 20th National Congress in 2022, President Xi Jinping underscored "ensuring the security of food, energy and resources, and key industrial and supply chains" as a central task for national security and social stability, deliberately placing food at the very top. In June 2024, China also enacted the Food Security Law. Underlying this obsession are deep historical scars. The Great Famine of 1959–1961 caused an officially estimated 30 million deaths, with actual casualties believed to be even higher. Foreign Affairs points out that approximately 15% of China's current population belongs to the generation that lived through that era firsthand.

[What Can Be Endured and What Cannot]

According to Foreign Affairs, Beijing has steadily built up contingencies regarding energy. In 2003, former President Hu Jintao warned of the so-called "Malacca Dilemma," cautioning that foreign powers could blockade the Strait of Malacca, through which most of China's crude oil imports transit. Since then, China has secured vast strategic petroleum reserves, and in an emergency, it could scale up crude imports from Russia or operate a shadow fleet to evade sanctions, much like Moscow. On semiconductors, China is also stockpiling critical components while rapidly accelerating domestic substitution.

Food, however, presents a different reality. While domestic production of the three major staple grains—wheat, rice, and corn—covers over 90% of consumption, items like soybeans, beef, and barley remain heavily reliant on overseas supply. The share of imports in China's overall food supply jumped from 6% in 2000 to 34% in 2020, and is projected to reach 41% by 2030. The era of subsisting purely on grain has ended; between 1962 and 2024, the proportion of meat in the Chinese diet increased 18-fold.

At the epicenter of this dietary structure sits the soybean. Soybeans serve as a high-protein feed ingredient that cannot be entirely replaced by other grains or synthetic amino acids. If soybean supplies are cut off, the pork and poultry farming sectors will collapse in tandem. Soybean oil accounts for nearly half of China’s cooking oil market, and alternative candidates like palm oil and rapeseed oil are also mostly imported, carrying identical maritime transport risks.

Recent statistics demonstrate that this dependency has only deepened. According to the General Administration of Customs of China, soybean imports in 2025 reached an all-time high of 111.82 million metric tons, up 6.5% year-on-year. According to an analysis by Fred Gale, an agricultural economist specializing in China, domestic production in the same year stood at 20.91 million metric tons, leaving the soybean self-sufficiency rate at a meager 16.2%.

Structural factors prevent China from expanding its own soybean cultivation. Farmland is simply not abundant enough to broaden soybean acreage while simultaneously maintaining staple grain self-sufficiency. Furthermore, vast tracts of viable arable land have already been repurposed for urbanization and industrialization. In the arid northern regions, planting corn or wheat yields significantly higher harvests and financial returns per unit of land. Consequently, imports remain the only viable option, yet major soybean exporters are concentrated almost entirely in the Western Hemisphere. Following the 2018 U.S.-China trade war, China reduced the U.S. share of its domestic supply from 40% to around 20%, filling the gap with Brazilian imports. In 2025, Brazilian imports surged to 82.33 million metric tons, accounting for 73.6% of total soybean imports—a shift heavily driven by China halting U.S. purchases for five months that year. Although sources were diversified between two players, the fundamental fact remains unchanged: both lie across the Pacific Ocean.

Shifting the primary supplier to Brazil did not mitigate the risk. Brazil grapples with deficient infrastructure and frequent natural disasters. In May 2024, severe flooding in the southern state of Rio Grande do Sul wiped out an estimated 2.71 million metric tons of soybeans, according to the state agricultural agency Emater. Distance poses another major hurdle. From Brazil’s Port of Santos to Guangzhou spans over 16,000 kilometers, requiring roughly 45 days at sea. Soybeans are highly vulnerable to moisture and often arrive spoiled after long voyages; for the same reason, they cannot be stored for extended periods. As a result, should imports be disrupted, domestic stocks could be completely depleted within months. This represents Beijing’s greatest dilemma.

[Supply Chains Severed Even Without a Blockade]

The most extreme scenario involves the U.S. Navy intercepting cargo vessels sailing from the Western Hemisphere to China. Lacking naval bases or forward-deployed forces in Latin America, China possesses few effective means to counter such an interdiction. However, Foreign Affairs highlights that China would suffer a crippling blow even in the complete absence of a formal blockade.

Once combat erupts across the Pacific, marine insurance premiums will skyrocket, and commercial carriers will refuse to operate. The precedent was set post-2024, when missile threats from Houthi rebels in Yemen caused insurance rates across the Red Sea route to surge. In a full-scale Pacific war where major navies clash with no alternative bypass routes, the commercial fallout would dwarf that of the Red Sea. Under those conditions, the long-haul route hauling soybeans from Brazil to China would naturally become commercially unviable for most shipping operators.

Beijing could offer state guarantees or premium subsidies, yet many shipping companies from the United States and allied nations would still likely reject China-bound cargo, citing international condemnation for aiding a hostile regime, crew safety concerns, and the risk of future sanctions. Chinese analysts point to their domestic merchant fleet as an alternative; state-owned shipping giant COSCO controls 468 dry bulk carriers. Yet during wartime, this fleet would have to transport essential raw materials like coal and iron ore, construction materials, and military logistics. Skilled personnel capable of preserving soybean cargo quality throughout a long transoceanic voyage would also be in short supply. Detouring to avoid combat zones would prolong the transit well beyond the roughly 40-day threshold soybeans can withstand, virtually guaranteeing that shipments would arrive rotted. China is caught in an inescapable catch-22.

[Empty Silos, Crumbling Trust]

A war would not instantaneously trigger an acute food crisis. The government could initially release national reserves of soybeans and frozen pork, while lowering soybean content thresholds in livestock feed to keep farming operations afloat. While livestock growth would decelerate and meat output drop, this strategy could buy several months of breathing room.

A far more plausible scenario, however, is that consumer panic-buying combined with logistical paralysis would deplete strategic reserves far ahead of schedule. The integrity of the stockpiles themselves is open to doubt. Over the past decade, recurring scandals have revealed emergency provincial grain silos sitting completely empty due to graft or stuffed with spoiled grain. The CCP Central Commission for Discipline Inspection (CCDI) launched an intensive crackdown on corruption within the grain procurement and sales sectors in August 2021, yet acknowledged in a January 2023 document that corruption in the sector was actually worsening. A 2013 official probe even uncovered schemes where operators mixed sand into grain supplies. Citizens who distrust state silos will inevitably resort to panic hoarding at the first whiff of crisis, and whatever supplies remain will almost certainly be diverted to party elites first.

As conflict drags on, the repercussions will compound step by step. Poultry farms, which rely overwhelmingly on soybean meal for dietary protein, will be the first to collapse, destabilizing egg supplies. Pork shortages will quickly follow, and cooking oil prices will spike, shattering everyday life in restaurants and households alike. Faced with hoarding, widespread protests against inflation and shortages, and systemic embezzlement of supplies by local officials, Beijing would ultimately face overwhelming pressure to terminate the war—this is the conclusion reached by Foreign Affairs.

The implicit social contract the Chinese Communist Party maintains with its populace is "full bellies in exchange for political obedience." In a country where the generation scarred by the Great Famine is still alive, the disappearance of meat and cooking oil signifies far more than economic hardship; it strips away the very foundation of regime legitimacy. In this light, an invasion of Taiwan is a gamble that puts the survival of the CCP regime itself on the table, and should it devolve into a protracted conflict, the outcome verges on self-destruction.

The underlying paradox is equally telling. Throughout trade disputes, Beijing has routinely brandished halts on U.S. soybean purchases as a retaliatory weapon, yet that weapon is a double-edged sword. Cutting off American supply only deepens Beijing's dangerous reliance on a single nation, Brazil. Furthermore, its multi-year purchase commitments for tens of millions of tons per annum read less like economic leverage and more like an admission that China cannot survive without transpacific agricultural lifelines. Soybeans are not a strategic lever for China; they are its shackles.

This dynamic offers clear implications for South Korea as well. Viewing food as a strategic asset applies equally to maritime logistics and insurance markets surrounding the Korean Peninsula in the event of a Taiwan Strait contingency. Deterrence is never forged by raw combat capability alone. Maintaining strategic reserves capable of outlasting a protracted war and securing alliance-level logistical continuity—in essence, the capability to master time—have become the true core of deterrence.
