Vietnam is only behind India (86 percent), according to the Travel Confidence survey by American online travel agency Booking.com that polled 11,000 travelers in 11 countries and territories across the region between April and May.
China, one of the few places in the world sticking to a zero-Covid policy, came third, followed by Australia and New Zealand.
The survey found 62 percent of Vietnamese tourists plan to make one to two trips this year and 45 percent wish to visit famous tourist destinations near Vietnam with a three-to-eight-hour flight time.
A total 82 percent of surveyed Vietnamese respondents said they felt happy as Vietnam reopened its border to international tourism and lifted most Covid travel restrictions.
The biggest concern of Vietnamese travelers for now is high travel costs (53 percent), quarantine rules (36 percent), the possibility of contracting Covid (32 percent) while traveling and suddenly changing Covid entry regulations (31 percent).
Vietnam allowed free-quarantine entry since March 15 and also ditched Covid testing requirements.
