The official state-run newspaper in northeastern China's Jilin city, near the border with North Korea, on Wednesday published a page of "common sense" advice on how readers can protect themselves from a nuclear weapons attack or explosion.
Jilin Daily, a newspaper in northeast China, published the article on Wednesday, covering issues related to self-protection against nuclear radiation, South Korean news service News 1 reported.
The article does not directly mention there could be a nuclear attack from North Korea or any other country.
Beijing has advocated a "freeze-for-freeze" approach, and has stated joint military exercises in South Korea are increasing tensions with the North.
Tensions are running high on the Korean Peninsula, with Pyongyang continuing missile and nuclear tests as the U.S. holds drills with its regional allies near the North Korean border.
Cartoon illustrations of ways to dispel radioactive contamination were also provided, such as using water to wash off shoes and using cotton buds to clean ears, as well as a picture of a vomiting child to show how medical help can be sought to speed the expulsion of radiation through stomach pumping and induced urination.
People who find themselves outside during a nuclear attack should try to lie in a ditch, cover exposed skin in light coloured clothing or dive into a river or lake to try and minimise the possibility of instantaneous death, it said. "But at the same time, there is absolutely no reason to be alarmed", the Global Times said.
The United States has called for and have implemented sanctions against North Korea, a move that is squeezing the regime's energy supply.
The report describes in detail how risky nuclear weapons can be and what happens following the explosion.
South Korea's Joint Chiefs of Staff said the Guam-based bomber simulated land strikes at a military field near South Korea's eastern coast during a drill with US and South Korean fighter jets.
A Chinese daily has advised people living in a province close to North Korea on how to survive a nuclear attack.
The five-day drills that began Monday involve more than 200 aircraft, including six U.S. F-22 and 18 F-35 stealth fighters.
