All you have to is to use a switch statement on the keys and append the correct capitals to the correct capital arrays.

for (key, value) in world {
   switch key {
    case "BEL", "LIE", "BGR": europeanCapitals.apped(value)
    case "IND", "VNM": asianCapitals.append(value)
    default: otherCapitals.append(value)
   }
}
