Hampton Inn hotels in China were non-Hilton Honors participating likely due to franchise agreement with the local developer.
We reported on January 3 (read more here) that these hotels had become participating per update on program Terms and conditions the day before. Now, Hilton Honors sent out an email above to select program members on Friday.

I guess that initially Hilton had this arrangement with their Chinese developer to keep the daily rates as low as possible for the market and forgo the loyalty component. Not sure what changed?
Le Club AccorHotels members still need to avoid ibis hotels in China that are not part of their loyalty program.
