The South Korean government will send additional US$1.6 million to the earthquake and tsunami affected Asian countries, announced South Korean Foreign Minister Ban Ki-moon on Wednesday.
Seoul previously promised to donate US$600,000 to help those countries' rehabilitation.
"Four South Korean people were killed by the strong tidal waves, while, 11 missing and 17 injured," Ban told reporters in a year- end gathering on Wednesday.
Ban also said his ministry has received some 590 reports from family members who have lost contact with their relatives traveling in the affected and nearby countries.
The Foreign Ministry decided to send diplomats to Thailand's famous resort Phuket island to help its citizens there.
Meanwhile, the ministry asked South Koreans to refrain from traveling to the disaster-hit South Asian countries, citing fears of disease outbreaks.
Sunday's earthquake measuring 8.7 on the Richter scale in Indonesia triggered devastating tsunamis which hit a number of coastal nations across Southeast and Southern Asia and the death toll has reached over 60,000 so far.
