The majority of customers, 82.5 percent, were foreign tourists from Asia, Europe and North America. But the number of Vietnamese guests declined by 1.7 percentage points after an increasing briefly in 2014-16.

International arrivals were up 19.9 percent to 15.5 million in 2018, while the number of domestic tourists rose by 9.3 percent to 80 million, it added.
