Is "This deal with Hyundai was made necessary because of the South Korean government's wide ban on all Japanese "cultural products", which remained in effect until 1998 and ensured that the only way Japanese products could legally enter the South Korean market was through licensing to a third-party (non-Japanese) distributor (see also JapanKorea disputes)." a good answer to the question "Until how long did South Korea ban Japanese cultural products?"
yes
