Current blockade in the Strait of Hormuz is almost similar to what the US Navy could pull off during a war over Taiwan. China would lose about 45% of its seaborne oil and be forced to switch to Russian oil. Right now is probably a good chance to test how reliable these alternative energy routes are and how effective alternatives such as clean energy are compared to oil.
China's dependence on fossil oil import from Middle East is far less than people think. Over the last few decades, China has steadily developed alternate energy resources like solar, wind, nuclear, hydro etc and also building pipelines to Russia, plus China itself is an oil production country.
The import of oil to China in 2025 is not an indicator of China's annual consumption because this is the year China buy and hoard oil inventory, meaning they bought more oil than their needs, and build up strategic oil reserve in case of oil crisis, like what is happening right now.
Also if Europe totally stop importing oil from Russia, these oil will go to China.
In Taiwan AR, Japan and Korean will face critical oil import problem as they do not produce oil unlike China with large domestic oil reserve and strategic oil reserve.
Here is the fact. China used less than 1 % of oil in its 2025 electricity generation. In total energy consumption oils is only 20% and could be partially replace by coal.
And electrification in inland water transport and coastal transport and land transport (mainly heavy vehicles like trucks) could be spiked if needed to be. These leave major users of oil in China to ocean transports ships and airlines.
China is the only country in the whole East Asia with the least concern to oil crisis as a result of decades of strategic planning.
