China introduced export controls on more than a dozen gallium- and germanium-related materials vital in the manufacturing of chips, in the latest tit-for-tat move in a trade war with the US.
In a statement, the Ministry of Commerce claimed the move was driven by national security concerns, with domestic exporters of the listed materials requiring a licence.
The Ministry and the State Council will review applications and issue export licences. The controls are due to be introduced on 1 August.
Details of the plan were released a few days after the Dutch government announced similar curbs on exports of advanced chipmaking equipment, which come into force on 1 September.
The Dutch government’s move is seen as part of a wider campaign by the US to convince other nations to join it in clamping down on shipments semiconductors and manufacturing equipment to China.
