You may have a pollinating insect problem. If there weren't many pollinators or the weather was cool and rainy during the blooming season so pollinators weren't active, then the flowers may not have been pollinated and then aborted. Asian pear flowers aren't very attractive to honeybees, they have a stinky smell and are pollinated by flies. Next year try to notice what insects are visiting the flowers.

I had to remove many sacred cedars from our land because they were close enough to our orchard to possibly create issues for our fruit trees.
