Japan expanded its export controls to include cutting-edge chips and quantum computer-related technology, a move China warned could have a negative impact on trade between the two countries.

The Japanese government is expanding its list of export-controlled items to include advanced chips, lithography equipment and cryocoolers needed for the manufacture of quantum computers, according to draft revisions to the foreign exchange law.
