RIA Novosti news agency reports that more than 20,000 people have been evacuated from flood-stricken areas in Russia's far east, where the Amur river has burst its banks after heavy rain. The army and emergency workers have set up 166 temporary shelters across three regions, providing drinking water, hot food and medical supplies.
Near Blagoveshchensk, the capital of the Amur region, the Zeya river is usually just a few hundred metres wide. But now, the water stretches more than 10km (6 miles) from bank to bank, covering streets and gardens in several villages. A small dam is still holding, protecting the city, but local residents say if the waters rise further, this might not be enough.
The authorities have deployed thousands of troops and emergency personnel. They are calling for calm. Experts suggest the flooding will not get any worse over the next few days, but the weather forecast promises more rain later this month. The flood waters are not expected to fully recede until September.
Heavy rain since last Wednesday has caused floods in the north-eastern provinces of Liaoning, Jilin and Heilongjiang. Crops have failed across 256,000 hectares of farmland in the region, which is one of China's major bread baskets, Xinhua reports.
According to reports, almost 3,000 soldiers are helping with relief efforts for more than 8 million residents of the north-east, who have been affected by the floods.
China and Russia are working well together to fight flooding affecting both countries, central government says.
Here's a case where nations pull together in a time of need. Nobody can hope to battle against nature's forces alone. Sometimes the most desperate situations bring out the best in people. I'm sure many people are placing themselves at risk to help others, although the stories might remain untold.
Unfortunately, these same circumstances bring out the worst in those greedy individuals who seek to take advantage of other people's misfortune. The relatively few soldiers left to guard properties can't hope to prevent all looting.
The world's population is full of good and bad.
I've only once experienced a flood. Mounting water seeped into my home in Victoria, Australia. The water came through the front door and rose about two inches. I can't remember the fear I must have felt 50 years ago. These things fade if they're unimportant. My strongest memory is of trying to save my precious possessions from water damage. This is what will worry the Chinese and Russian people when they are evacuated from their homes. To save their lives, they must leave everything behind, knowing they may never see it again.
