The area remains closed as thousands of citizens evacuate to safety, and as emergency personnel begin search and rescue operations. Officials on Chinese social media posted that the area may re-open later this week after safety assessments are carried out.

Summer flooding is not uncommon in the region -- but this year has seen the worst floods in decades, destroying the homes and livelihoods of millions of people as the country struggles to revive an economy battered by the coronavirus pandemic.

The floods, which began in earnest in June, have impacted at least 55 million people -- more than the entire population of Canada.

At least 443 rivers nationwide have been flooded, with 33 of them swelling to the highest levels ever recorded, the Ministry of Water Resources said in July.

On Wednesday, the Ministry of Water Resources raised the national emergency response alert for flood control to level 2 -- the second highest in a four-tier system.

The majority of these flooding rivers are in the vast basin of the Yangtze River, which flows from west to east through the densely populated provinces of central China. The river is the longest and most important waterway in the country, irrigating large swathes of farmland and linking a string of inland industrial metropolises with the commercial hub of Shanghai on the eastern coast.

The flooding has not only washed away people's homes and communities -- but their farms and food supply as well. Last month, floods destroyed thousands of acres of farmland in Jiangxi province alone. The broader Yangtze River basin accounts for 70% of the country's rice production.

China's Ministry of Emergency Management pegs the direct economic cost of the disaster at $21 billion in destroyed farmland, roads and other property.

Beijing has so far been able to secure food supplies by importing vast amounts of produce from other countries, and by releasing tens of millions of tons from strategic reserves -- but analysts warn that such measures can only be useful for so long.
