The tourism department of Hanoi announced Tuesday that they have suspended the travel company which organized the ill-fated tour that left 12 tourists dead in Ha Long Bay last month.
The Nu Hoang Company (AZ Queen), which offers low-cost tours to foreigners, has also been fined VND15 million (US$719) for illegally running international travel services.
Meanwhile, in his proposal to the Hanoi Department of Sports, Culture and Tourism, chief inspector Nguyen Thanh Phong suggested revoking the company's license indefinitely.
Nguyen Van Hien, director of the company, should have his licensed withdrawn as well, and no license of international tourism should be granted to any business run by him, according to the proposal.
Phong asked the department to to cooperate with related agencies in investigating other travel agents in Hoan Kiem District, where AZ Queen is located.
According to inspectors, some of the 21 tourists on the Truong Hai 06 boat, which sank in Ha Long Bay at dawn on Feb 18, directly bought the tour from AZ Queen, while others made their purchases via the company's agents.
It was found later that the accident, which killed ten foreigners and two Vietnamese, happened because the valve that allows water to come into the boat to cool the engine wasn't closed properly before the crew went to bed.
The Truong Hai Company, which owns the boat, was also suspended, while the boat's captain and chief engineer were detained for further investigation.
