I want to know the answer to the following question:
How could Japanese products only enter South Korea?
All the background I'm provided with is that "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 Japan–Korea disputes).". Is that enough to answer the question?
Answer: yes
