They tourists arrived in Phu Quoc on private jets that landed Thursday and Friday on a four-day tour package.
They are relatives of leaders at a Lao private conglomerate which has a representative office in Vietnam, said Nguyen Vu Khac Huy, general director of Vina Phu Quoc Travel Company, which has brought the Lao tourists to Phu Quoc.
The tourists are staying at the Vinpearl Phu Quoc Resort and will visit tourist attractions including the Phu Quoc night market, Vinpearl Safari wildlife conservation park and play golf at Vinpearl Golf.
On New Year's Eve, they will be invited to attend a countdown event with fireworks shows and other entertainment events.
The vaccine passport program requires all tourists to furnish certificates showing they have been fully vaccinated or have recovered from Covid and tested negative for the novel coronavirus within 72 hours before departure.
Kien Giang Province, where Phu Quoc is located, is one of five localities to get the green light from the government to welcome back fully immunized tourists from November onwards, alongside Quang Nam, Khanh Hoa, Quang Ninh, and Da Nang.
In more than a month after the partial reopening of international tourism following nearly two years of closure over the Covid-19 pandemic, Vietnam has welcomed over 3,500 foreign visitors on special tour packages.
