China-North Korea ties strained over nuclear tests

The BBC's Martin Patience said there is "growing frustration in Beijing" over North Korea's nuclear programme, with China eager to resume six-party talks to resolve the situation.

China has called on all sides to show restraint after Pyongyang threatened to conduct another nuclear test in retaliation for the tightening of international sanctions.

North Korea's actions comes two days after the UN Security Council announced further sanctions after Pyongyang test-fired a long range rocket last month.
