At least 43 people have been killed and several others are missing after floods in storm-hit central Vietnam.
China has been severely hit by bad weather this summer
Soldiers were helping to rush emergency supplies to some of the 200,000 people whose homes have been swept away or damaged by the flood waters.
The region is braced for further bad weather as tropical storm Pabuk heads across the South China Sea to China.
China has seen months of bad weather, which officials say has affected some five million people.
Natural disasters left 712 people dead and 163 missing in July alone, the Chinese Ministry of Civil Affairs said on its website.
'Nothing to eat'
Vietnam is counting its dead after days of tropical storms triggered flooding in several central provinces.
At least 15 people died in the worst-hit province of Ha Tinh, which saw some 60cm (24 inches) of rainfall.

The coffee-growing Central Highland province of Daklak saw its death toll rise to 14, with seven still missing, on Thursday.
At least four people died in Quang Binh province, and there were reports of a further 11 deaths in other provinces.
Officials said their pressing concern was to ensure relief aid was delivered to the many thousands affected by the floods.
"At present, hunger is something worrying us the most, because for the last few days people had to escape the water and many of them had nothing to eat," provincial official Nguyen Ngoc Dien was quoted by the Associated Press as saying.
The authorities said they hoped to start resuming train services between the north and south later on Thursday.
Vietnam seems to have escaped the worst of tropical storm Pabuk, which lashed the Philippines and Taiwan earlier in the week.
The storm is reported to be picking up strength as it heads towards southern China's Guangdong province, where it is expected to make landfall later on Thursday.
With news that another tropical storm is also forming, hundreds of thousands of people have been evacuated from China's southern provinces as weather forecasters warn of further flooding and landslides.
Several areas of China have been hit by flooding, landslides and drought this summer, which the ministry of civil affairs said were "far worse than last year".
Red Cross officials are assessing the clean-up effort in two areas which were badly hit last month - the central province of Anhui and Chongqing city, in the south-west.
Chongqing received more than 26cm (10 inches) of rain in 24 hours - the most in such a short period since records began more than a century ago.
The International Federation of the Red Cross has launched an appeal for financial aid to fund relief and reconstruction.
"A major reconstruction effort is needed," a spokesman told the BBC. "It will be difficult to get the amount of money that is required, and the government can only do so much."
