This Could Be Big

From the Washington Post:  China will suspend all imports of coal from North Korea until the end of the year, the Commerce Ministry announced Saturday, in a surprise move that would cut off a major financial lifeline for Pyongyang and significantly enhance the effectiveness of U.N. sanctions.
Coal is North Korea’s largest export item, and also China’s greatest point of leverage over the regime.
The ministry said the ban would come into force Sunday and be effective until Dec. 31.

It will be interesting to see what North Korea does.
Do they start calming down and become more civilised? 
Or will they react like an injured animal: kick, yell and fight back physically?
But good for China for doing this.
