China does grow white garlic (in Shandong province), but in very limited quantities. In fact, asparagus of any sort is quite a recent find here. Five years ago I was lucky to see it once a year; now the regular green kind is in most supermarkets.
I seriously doubt much, if any, white asparagus is exported. At least for now.
I still prefer English asparagus in its short season. Perfection.
