Why is the Golden Eagle more successful than the JF-17?

With the latest news.. the Golden Eagle will be flying with four air forces, with over 80 built so far. Although its a trainer, all of the export customers have ordered the combat version
the jf-17, about 50-60 built and in service with just Pakistan.

I could argue that the JF-17 is the the better performing aircraft with greater potential for combat roles, less restrictions than KAI, but what has been limiting its export success?
why Koreans can, and Chinastan can’t?
