South Korea said Friday it will send US$200,000 in emergency humanitarian assistance to help victims in flood-stricken Cambodia, pledging more aid for the flooded Southeast Asian region. Cambodia and neighboring Thailand are struggling to cope with their worst monsoon floods in more than a decade, with the combined death toll in the two nations approaching 500. \"The government is closely monitoring the flood situation in Southeast Asia and will actively respond to help if more damage occurs,\" foreign ministry spokesman Cho Byung-jae said in a statement. Early this week, South Korea announced $200,000 in flood aid for Thailand.
