Time to address root cause, drop double standards

The terrorist attack in Paris last Friday that killed 129 people and the bombing of Russian jet on Oct 31 in which 224 lives were lost are just the latest atrocities that should be condemned by the whole world.

After the Paris attacks, cities around the world lit their landmarks in the colors of the French flag to show their support for the French people. That also included the Oriental Pearl TV Tower in my home city of Shanghai.

But while expressing sympathy for the victims of the terrorist attacks, many Chinese are asking what has caused the growing number of extremists like those of the Islamic State group.
