Blokkade verbiedt reserveringen via Booking.com

Dat de blokkade tegen Cuba ook tot bij ons te voelen is, blijkt nogmaals uit volgend voorval: 
Een toerist die een casa particular in Cuba wou boeken, kreeg het volgende mailbericht toegestuurd: 

Dear M.
Thank you for choosing Booking.com.
We are writing to you regarding your reservation XXXXXX at XXXX…
Due to the sanction by the U.S. State Department, your reservation has been cancelled today. If any pre-payment has been collected, the refund process will start immediately.
Booking.com and customers are no longer allowed to do business with sanctioned accommodations in Cuba. We are sorry for the inconvenience this has caused you. 
For your convenience, we recommend making a new reservation on non-sanctioned properties by clicking in the link below….
Again, accept our apologies and please feel free to contact us with any additional questions.
Kind regards,
