Typhoon Damrey has killed at least 27 people after pummelling central and southern Vietnam, just days before Donald Trump heads to the country for the APEC summit of Asia-Pacific leaders.
Damrey reached land at 4am (local time) with winds gusting at up to 90 kilometres per hour that damaged more than 40,000 homes, knocked down hundreds of electricity poles and uprooted trees.
The communist state's search and rescue committee said 22 people are missing after the storm, while 626 houses had been collapsed entirely. More than 33,000 people had been evacuated.
The storm made landfall near the city of Nha Trang, which is about 500 kilometres south of the coastal city of Danang, where the Asia-Pacific Economic Cooperation (APEC) summit is taking place next week.
Danang itself also suffered. A gateway proclaiming "Welcome to Danang" collapsed in the storm, state media said.
Authorities in the area called on citizens to volunteer to help clean up.
The city will host US President Donald Trump from November 10 as well as China's Xi Jinping, Russia's Vladimir Putin and counterparts from other APEC members.
Nha Trang, a coastal resort city, faced the brunt of Damrey's impact, with fierce rain and extreme winds knocking over scooters and flooding roads.
Earlier the Government said six ships had capsized with 61 people on board in the South China Sea, and 25 people had been rescued, but gave no details on the possible fate of the others.
The storm moved from the coastal area into a key coffee-growing area of the world's biggest producer of robusta coffee beans.
Traders had expected the storm to delay harvesting, but were not sure whether it would damage the crop.
The Government said more than 40,000 hectares of crops had been damaged, including sugar cane, rice fields and rubber plantations. More than 40 flights were cancelled.
Floods killed more than 80 people in northern Vietnam last month while a typhoon wreaked havoc in central provinces in September.
The country of more than 90 million people is prone to destructive storms and flooding due to its long coastline.
