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. Companies will need licences to export the items to prevent their use in weapons or their development, economy ministry officials have said. Advanced chips could be diverted to increase the computational capabilities of precision-guided weapons, while quantum computers could be used to break encryption. The new curbs are scheduled to come into effect at the end of May. The move comes as the US looks to close loopholes to its restrictions on sales of chips used for artificial intelligence applications amid growing alarm in Washington over the possible re-export of Nvidia Corp semiconductors to China. Separately, Tokyo is also strengthening its exports controls by adding to its entity list. The ministry included 42 new entities worldwide to its list of foreign companies and organisations that would be subject to export oversight on any dual-use items. The additions come into effect on Feb 5, it said. A total of around 110 Chinese companies, research institutions and other entities are on the list.
