China blocks exports of helium, key for chipmaking, as Iran war squeezes supply
Summary
China has temporarily stopped exporting helium, a gas important for making computer chips and for medical machines. This move comes as global helium supplies are disrupted by the conflict in Iran, causing prices to rise and shortages worldwide.Key Facts
- China announced an immediate temporary ban on helium exports.
- Helium is essential for semiconductor (chip) manufacturing and cooling MRI medical machines.
- The Iran war, starting in February, has disrupted helium supply globally.
- China produces about 15% or less of its helium and imports much from Qatar, which supplies one-third of the world’s helium.
- The export ban aims to protect China’s local industries, especially chipmaking.
- China is increasing efforts to be self-reliant in technology amid competition with the U.S.
- Experts say China’s export ban may not strongly affect global helium supply since China exports little helium.
- The timing for helium supply to stabilize worldwide is still uncertain.
