The government of Vietnam, where Kajiki made landfall on Monday in the north-central region with wind gusts of up to 150km/h, reported on its state news outlet on Wednesday that seven people had died and 34 were injured, while rescue teams search for one missing person.
Hanoi, which had planned to evacuate 500,000 residents before the typhoon's arrival, also said some 10,000 houses were damaged or flooded.
The floods also affected more than 81,500ha of rice crops and killed about 2000 head of cattle.
Kajiki, which weakened to a tropical depression, also brought heavy rainfall on Tuesday to Laos and Thailand.
In the northern Thai province of Chiang Mai, the storm's effects caused the deaths of two people, while a search is underway for two others who are missing, the provincial Public Relations department reported Wednesday.
The fatalities in Thailand, where 10 injuries and flooding have also been reported in several northern regions, were due to a landslide in the village of Pang Ung.
Before striking these two countries, the typhoon affected more than 100,000 people as it passed Sunday over the southern Chinese island province of Hainan, where fire services conducted rescues, cleared debris and trees, and carried out cleanup work in several areas following heavy rain and winds.
