R and stata are clearly doing dif
I am not the person to answer your question, but have some suggestions:
Make your examples reproducible so others can confirm your results and explore
other issues you may not have seen. [1] [2]
Post your question on the R-sig-mixed mailing list, where mixed models experts

Dear colleagues!
We spent calculation of the gravity model in R and STATA software.
For calculations we used the standard package glmm in R (with parameter
family = quasipoisson)
and ppml in STATA.
Call the calculation procedure in R:
summary(glmm<-glm(formula=exports ~ ln_GDPimporter + ln_GDPex
