If not, then a 1 hour 40 min connection at LAX is pushing it as you are likely to need to collect bags and check-in again and if your inbound flight is late, then you may be in a spot of trouble. More so if your place of origin is not in the USA.

If you are able to check your bags all the way through to AAA from ZZZ (or at least to HKG from ZZZ), then if 1 hour 40 mins at LAX is a legal connection, do that.
