The South Korean government sent a medical team for Laos on Sunday to help those affected by the recent collapse of a dam and subsequent flooding.
Fifteen doctors and five support staff will be in Laos for 10 days to help prevent contagious diseases and provide treatment.
More than three thousand people are still stranded and roughly 130 people are missing.
On Saturday, Korea sent Laos basic necessities like blankets and hygiene kits.
The dam that collapsed was built by a joint venture that included two Korean companies.
It's still not clear why the structure broke.
