The Chinese Ministry of Environmental Protection (MEP) has ended the emergency radiation monitoring following the nuclear test conducted by North Korea saying the test had no impact on China.
North Korea announced on January 6 that it had tested a hydrogen bomb.
The MEP then launched its second-highest level of emergency response, monitoring radiation levels along the country's northeast border.
The checks found radiation to be within the normal range, and no artificial radioactive nuclides were detected in air samples, state-run Xinhua news agency quoted MEP as saying.
