For example I have two lists of such structure
 
        L1={{"Australia",a1}, {"USA",a2}, {"Norway",a3},...}
        L2={{"Russia",b1}, {"Norway",b2}, {"Japan",b3},...}
I would like to sort contries of the list `L2` in the contries' order of `L1` to compare it entirely (I mean the values matching for each country). Could you render me some assistance in accomplishing it?! Thus I would like to gain smth resembling this as a result where `L3` is the sorted `L2`:
 
        L1={{"Australia",a1}, {"USA",a2}, {"Norway",a3},...}
        L3={{"Australia",b26},{"USA",b13} {"Norway",b2},...}
