MACAU ~ Tourism is on a roll in tiny gambling haven Macau, with a record 22 million people visiting the southern Chinese territory’s booming casinos in 2006, tourist chiefs said.

The former Portuguese enclave of just 450,000 people was swamped by 12 million tourists from mainland China alone.

Together, tourists spent a massive US$21 billion on gambling, hotels, food and booze – all of which made Macau the world’s most profitable casino city, beating even Las Vegas’ famous strip.
