On June 29, China announced that it had added more Japanese companies and organizations to its export control list, with 40 new entities in total.
China said these entities might use some products for military purposes, so exports need to be restricted.
These products are called "dual-use items," meaning they can be used for civilian purposes in normal times but may also have military uses, such as rare earths, batteries, machine tools, and semiconductor equipment.
The Japanese government is very dissatisfied with this and has already lodged a protest with China, asking it to cancel these measures.
China said this move mainly targets a small number of Japanese entities and will not affect ordinary trade.
Recently, China-Japan relations have remained relatively tense, and the two sides' differences over security and military issues have been growing.
Analysts believe that China's tighter controls are also related to important resources such as rare earths, because many countries are now trying to reduce their dependence on Chinese supply chains.
