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},...}

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 countries of the list L2 in the countries' order of L1 to compare it entirely (I mean the values matching for each country). Thus I would like to gain something 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},...}
