Hi,

Try this. 
map<String,Object> objMap= (map<String,Object>)JSON.deserializeUntyped('{"data": [{"country": "usa", "value": "usa-co" },{"country": "Australia", "value": "Aus-Mo" },{"country": "Germany", "value": "Gem-flo"}]}');
List<Object> objList = (List<Object>)objMap.get('data');
map<String,String> countryNameValueMap = new map<String,String>();

for(Object obj : objList){
    map<String,Object> contryMap = (map<String,Object>)obj;
    countryNameValueMap.put((String)contryMap.get('country'),(String)contryMap.get('value'));
}

The countryNameValueMap will give you the below result
  
{Australia=Aus-Mo, Germany=Gem-flo, usa=usa-co}

Your code statement will give you illegal assignment error.

 Anyhow you can make it like below.

map<string, List<string>> conMap = new manp<string, List<string>>();
