Extinction is (much) more severe than extirpation. It's not guaranteed or even likely that using genetic engineering to eradicate a species in the US would also eradicate it in China. Suicide genes shouldn't last long in a population. If accidentally introducing one or two self-destructing lanternflies to China (via shipping) was going to kill them all, we'd probably be rid of mosquitoes already.
