China has announced a ban on the export of rare minerals essential for the manufacture of electronic components used in products like iPhones. This measure is part of an escalation in the technological war between China and the U.S.

Affected minerals:

- Gallium: used in semiconductors

- Germanium: used in infrared technology and fiber optics

- Antimony: employed in military explosives

- Superhard materials: used in various industrial applications

China is the world's leading supplier of these minerals, and the ban could significantly impact the production of advanced technology in the U.S. The measure comes after restrictions imposed by the Biden administration on advanced American technology to China.

Impact:

- The global technology industry may be affected, especially the production of iPhones and other electronic devices.

- Companies may need to seek alternative suppliers, which could take time and increase costs.

- The measure may also affect the global supply chain, leading to greater economic instability.

China criticizes the U.S. technological restrictions, calling them "illegal" and arguing that they harm the international economic and trade order.
