China steps up control of rare-earth exports citing ‘national security’ concerns

China has increased restrictions on exports of rare earths and related technologies as Beijing tightened its grip on the products that are critical for use in smartphones and fighter jets.

China’s commerce ministry announced the restrictions on Thursday, arguing damage had been caused to its “national security” from exports of the technologies – both directly or indirectly – to foreign military.

The restrictions require government permission for the export of technology used to mine, process or recycle rare-earth minerals or make magnets from it, which could have dual use. The ministry noted that permission may not be granted.

The new rules come amid tense US-China trade talks, and weeks before an expected meeting between Xi Jinping and Donald Trump on the sidelines of the Apec summit in South Korea.

Rare earths and rare-earth magnets are used in products ranging from consumer electronics and cars to jet engines and radar systems. China controls about 70% of the world’s rare-earth mining and almost all of its separation and processing and magnet manufacturing.

The restrictions also ban Chinese nationals and Chinese companies from assisting in the same processes overseas. Foreign manufacturers using Chinese machinery or components overseas are now expected to seek permission, although it was unclear how that would be enforced.

Companies hoping to export items that have even small traces of Chinese-sourced rare-earths elements must get ministry approval. Those with previously issued export licences for potential dual-use items were encouraged to “proactively present” the licences for inspection.

Most of the new rules, which took immediate effect on Thursday and expand on export restrictions first announced in April, make clear that Beijing is targeting particular industries. The announcement specified that overseas defence users would not be granted licences, the ministry said, while applications related to advanced semiconductors would only be approved on a case-by-case basis.
