South Korea approved remdesivir for general, ongoing import.
The drug safety ministry announced there's a need for continuous supplies of the antiviral product, made by U.S.-based Gilead Sciences.
Preliminary reports have shown remdesivir can shorten the recovery time for severe cases of COVID-19 by 30 percent.
The ministry also approved six additional brands of test kits that can confirm infections within an hour.
These will be used for emergency cases when patients might need immediate surgery.
