How China responded to previous North Korean nuclear tests
Beijing has consistently criticised its neighbour’s action but has stressed the importance of diplomacy

China has frequently been urged by other countries – including the United States and Japan – to do more to rein in North Korea – but after Pyongyang’s five previous nuclear tests it has not gone further than issuing condemnations and supporting UN sanctions.
On Monday Geng Shuang, a spokesman for the Chinese foreign ministry, said it had been made clear to North Korea that China opposed the latest test – the most powerful yet – and reiterated China’s support for talks to reduce tension on the Korean peninsula.
The response was broadly in line with the measured response to previous tests.
Here’s how Beijing responded to those tests.
October 2006
Pyongyang’s first nuclear weapons test was on October 9, 2006 – a move that triggered swift international condemnation.
The test produced an explosion of less than one kiloton, or the equivalent of about 1,000 tonnes of TNT.
