We study the effect of finite 't Hooft coupling corrections on the imaginarypotential and the thermal width of a moving heavy quarkonium from the AdS/CFTcorrespondence. To study these corrections, we consider $\mathcal{R}^4$ termsand Gauss$-$Bonnet gravity. We conclude that the imaginary potential of amoving or static heavy quarkonium starts to be generated for smaller distancesof quark and antiquark. Similar to the case of static heavy quarkonium, it isshown that by considering the corrections the thermal width becomes effectivelysmaller. The results are compared with analogous calculations in a weaklycoupled plasma.
