The Chinese government is urging Japan to halt semiconductor export controls.
China's latest request comes as Japan, along with the Netherlands, in January agreed to match US export controls that will limit the sale of some chip-making tools to China.
They have placed restrictions on the export of 23 types of semiconductor manufacturing equipment.
The US imposed the restrictions last year aiming to slow China's work on supercomputers that can be used to develop nuclear weapons and artificial intelligence systems.
Japan has not singled out China in its statements about the export controls, saying only that it is fulfilling its duty to contribute to international peace and stability.
