China has ended monitoring the environment in its northeast border regions on Sunday in response to a nuclear test conducted by North Korea on September 3.
The Ministry of Environmental Protection's (MEP) National Nuclear Safety Administration said "we have stopped our emergency response because North Korea's sixth nuclear test did no damage to China's environment. "
The emergency response ended at 6pm on Sunday, the MEP said on its website.
The MEP led other government agencies in evaluating the radiation levels in China's northeastern border areas for eight days.
The radiation levels were normal, the MEP said.
The MEP conducted its emergency response on September 3 shortly after North Korea announced it had successfully detonated a hydrogen bomb that can be placed in an intercontinental ballistic missile.
The National Nuclear Safety Administration said it will continue to monitor the area's radiation level on routine basis.
