American brands, especially if they're perceived as luxury or have limited or no availability in China would be a hit.

I like the idea of a more permanent gift like a handbag rather than or in addition to some F&B that can't be found in China. It depends on how well you know her tastes.

In the USA, we would often bring a house-type gift for a home visit, but Chinese apartments might not have much space and she might not do much home entertaining, so a fancy serving dish, tray, large flower vase, crystal wine or liquor decanter, etc. might be problematic.

It should be something that can be packed easily and survive the trip without damage.

If all else fails, you can buy a fancy bottle of cognac or scotch in airport dutyfree if you're flying nonstop. You might get a better selection if you can order in advance; some stores require that this be done seven days ahead and others only 24-48 hours.
