Maintainer of that range. Currently it’s unallocated, pending reallocation to a new product line shortly. It’s not announced by us. It appears China Mobile (AS40676) attempted theft via unauthorized announcement (RADB listed). I’ve just enabled RPKI & ROA on that range.
Thanks for the notification, sorry for the delay it came indirect as we are not a member here. For further correspondence could I perhaps request a contact at the technical contact or abuse contact for the range.
