st: Non omitted variables with individual fixed effects

Dear statalisters
I am running a regression on a cross section basis. I use country
specific fixed effects and, at the same time, I introduce country
specific variables in the regression:
xi: reg logCBT log_dist comlang_off gdp_part i.part i.decl , robust
where decl and part are the variables identifying partner and
declarant countries, and gdp_part is the GDP of the partner
My question is: why is gdp_part not excluded? This variable is
constant for the partner and I was expecting Stata to drop it. Is the
command incorrectly specified?
Thanks a lot,
Estrella
