CHEONAN AND YEONPYEONG.

Divergent responses to the sinking of the ROKS Cheonan and the shelling of Yeonpyeong Island in 2010 have raised tensions in Northeast Asia. China's enabling response appeared to write North Korea a blank cheque for further provocations; but Beijing has in fact been constrained by fear of destabilisation of the Kim regime.
