st: Sum of specific observations of the same variable

Hello there,
I have data on bilateral trade that shows the export flows from country i
(reporter) to country j (partner). For example:
reporter partner trade
Albania Austria X1
Albania Armenia X2
. . .
. . .
. . .
Austria Albania Xn
Austria Armenia Xn+1
. . .
. . .
I want to find the total trade flows between the countries.In other words,
I want to sum the trade from one pair (eg Albania Austria) plus the trade
from the inversed pair (eg Austria Albania) for around 6000
observations..Is there any way I could possibly do this?
Thanks,
Andrew
