SEOUL -- South Korea may control the export of DRAM chips to Japan in retaliation for Tokyo's own export curbs, a director of the presidential Blue House told a local radio station.

Kim Hyun-chong, deputy director of the National Security Office, said that Seoul could use the constraint as a weapon against Tokyo, citing South Korea's control of more than 70% of the global market for DRAM chips.
