Stephen replied to this. Let me expand on it a bit. Basically what Stephen is suggesting is to have the same dataset stored in a second file. This second data set will however have country 2 renamed to country 1 and vice versa. Then a joinby command on the two datasets should do the job. The joinby variables would be country 1 and year. If you want to be sure whether joinby is doing it right, you might want to add the unm(both) option in the joinby command, just to see if this is you are getting what you want. I think this is correct.
