I think what you can do is this
1. Do a query based on UNPIVOT to get the data as rows instead of columns
For that you can use a query like this
IF OBJECT_ID('temp') IS NOT NULL DROP TABLE temp
CREATE TABLE temp
Country varchar(100),
Val decimal(25,5)
DECLARE @CountryList varchar(3000),@SQL varchar(max)
SELECT @CountryList = STUFF((SELECT ',[' + Column_Name + ']' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = '<SalesTableNameHere>' FOR XML PATH('')),1,1,'')
SET @SQL= 'SELECT * FROM <SalesTableNameHere> t UNPIVOT (Val FOR Country IN (' + @CountryList + '))p'
INSERT temp
EXEC (@SQL)
Once this is done you'll get data unpivoted to table
Then you can use a execute sql task with query like above
SELECT DISTINCT Country FROM Temp
Use resultset option as full resultset and store the result to an object variable
Then add a ForEach loop container with ADO enumerator and map to the object variable created above. Have variables inside loop to get inidvidual country values out.
Inside loop place a data flow task. Use a variable to store source query , make EvaluateAsExpression true for it and set Expression as below
"SELECT Val FROM Temp WHERE Country = " + @[User::LoopVariable]
Where LoopVariable is variable created inside loop for getting iterated values
Inside data flow task place a oledb source, choose option as  SQL command from variable and map to the above query variable.
Link this to flat file destination create a flat file connection manager. Set a dynamic flat file connection using expression builder. Make it based on a variable and set variable to increment based on loop iteration
The core logic looks similar to this
