The Strait of Hormuz, a critical artery for global energy supplies, is effectively closed due to the escalating conflict between the U.S. And Iran, sending shockwaves through Asian economies. As oil exports from the Middle East plummet – down 61% in recent weeks, according to maritime tracking consultancy Kpler – China appears uniquely positioned to weather the storm. Even as nations across Asia scramble to conserve energy, Beijing has been quietly preparing for a crisis of this magnitude for years, a strategy rooted in a national imperative to secure its energy future.
The groundwork for this resilience was laid as early as 2021, when President Xi Jinping reportedly emphasized the necessitate for China to secure its energy supply “in its own hands,” during a visit to a domestic oilfield. This directive has translated into a multi-pronged approach encompassing massive strategic reserves, diversified import routes, and a rapidly expanding domestic renewable energy sector. The current crisis is testing that preparation, and early indications suggest it is paying off.
A Strategic Reserve and Diversified Supply Lines
China’s energy system possesses “significant buffers,” according to Michal Meidan, head of China energy research at the Oxford Institute for Energy Studies. These buffers include substantial reserves of both oil and liquefied natural gas (LNG), coupled with a robust domestic energy production capacity. While China typically imports around half of its crude oil from the Middle East, its reliance is less acute than that of other major Asian economies like Japan, which sources approximately 95% of its oil from the region.
Despite the ongoing war, Iran continues to ship oil to China, remaining its primary buyer. Imports have experienced only a marginal decrease, falling from 1.57 million barrels per day in February to 1.47 million barrels per day in March, according to Kpler estimates. Chinese state-owned firms are actively navigating alternative routes to secure supplies. The supertanker Kai Jing, for example, recently diverted to a Red Sea port to pick up Saudi crude, bypassing the Strait of Hormuz, and is expected to arrive in China in early April, as reported by the Chinese media outlet Caixin.
Building a Stockpile for a Rainy Day
Beyond diversified supply lines, China has quietly amassed a substantial strategic oil stockpile. While Beijing does not publicly disclose the exact size of its reserves, estimates place it around 1.4 billion barrels, according to Columbia University’s Center on Global Energy Policy. This massive hoard provides a crucial cushion against disruptions in global supply, allowing China to mitigate the immediate impact of the crisis.
In response to the outbreak of hostilities, Beijing instructed its domestic refineries to halt exports, prioritizing internal needs. This move underscores the government’s commitment to safeguarding its energy security during a period of heightened geopolitical instability.
Investing in a Renewable Future
China’s long-term energy strategy extends beyond securing fossil fuel supplies. The nation is aggressively investing in renewable energy sources, aiming to reduce its overall dependence on foreign oil. More electric and hybrid vehicles are sold annually in China than in the rest of the world combined, according to the International Energy Agency. This shift towards electric mobility is reducing demand for gasoline and diesel, lessening the impact of oil price fluctuations.
The expansion of renewable energy capacity is also accelerating. Energy thinktank Ember estimates that wind, solar, and hydropower generated approximately 31% of China’s electricity in 2024. This growing share of renewable energy is providing a buffer against disruptions in fossil fuel supplies and contributing to China’s long-term energy independence.
Vulnerabilities Remain
Despite its advantages, China is not entirely immune to the effects of the crisis. Independent refiners, which are major importers of Iranian crude, remain particularly vulnerable. Industrial and chemical sectors reliant on LNG also face the prospect of higher prices and potential supply shortfalls. Meidan cautions that while a short-term disruption is manageable, prolonged instability and escalating prices could raise alarm bells in Beijing.
Releasing reserves, while possible, isn’t a simple solution. Meidan notes that China’s strategic petroleum reserve (SPR) mechanism has been tested only once, and a larger release would likely require a sustained supply shortage and significant price spike.
The situation remains fluid. As the US-Israel war on Iran continues, the global energy market will remain volatile. China’s preparedness offers a degree of insulation, but the longer the crisis persists, the greater the strain on its economy and the more challenging it will be for all nations. The next key development to watch will be the duration of the disruptions in the Strait of Hormuz and the extent to which alternative supply routes can effectively compensate for the lost capacity.
