My female parental unit tipped me off about this NYT arkle which is making waves:

A Chinese county along the border with North Korea is constructing refugee camps intended to house thousands of migrants fleeing a possible crisis on the Korean Peninsula, according to an internal document that appears to have been leaked from China’s main state-owned telecommunications company.
Three villages in Changbai County and two cities in the northeastern border province of Jilin, have been designated for the camps, according to the document from China Mobile. The document appeared last week on Weibo, a microblogging site.
The camps are an unusual, albeit tacit, admission by China that instability in North Korea is increasingly likely, and that refugees could swarm across the Tumen River, a narrow ribbon of water that divides the two countries.

The areas designated for the refugee camps were on state-owned land, and temporary housing had already been constructed at several sites, according to a local businessman who requested anonymity for fear of angering the local government.
Three county villages were named in the document as locations for the camps. The cities of Tumen and Hunchun will also house refugees, according to the businessman.
Tumen and Hunchun have for 20 years received defectors, who have managed to escape from North Korea into China. Many of those defectors travel on to Southeast Asia and eventually to South Korea.

Last week, the Jilin Daily, a provincial newspaper, advised residents on how to react in case of a nuclear explosion or radioactive fallout.
The advice included washing off radioactive dust from exposed body parts and shoes, and taking iodine tablets. The article noted that when the United States dropped an atomic bomb on Hiroshima, Japan, in 1945, more than 70,000 people were killed. Modern weapons are many times more powerful.

“It is highly possible that there is a conflict between North Korea and the United States now,” said Zhang Liangui, a professor of international strategic research at the Communist Party’s Central Party School. “What China does here is to be prepared for any kind of situation happening on the Korean Peninsula.”
In another sign of increased tensions, South Korea said on Monday that it would join the United States and Japan for a drill to practice tracking missiles launched from North Korean submarines.
