Chinese Government - A robber and a thief

On May 30, the Chinese government suddenly announced that it will increase stock trade interest by several times at midnight. Formerly when the press is asking the government agents, they all said that they won't raise the rate.

Then tragedy happened as the notorious, untrustworthy, and low government decided to rob all the people of China at midnight ...

After the event took place... most stocks fell at least 40~50% in the consecutive days.

Is there a world government/authority where I can sue the Chinese government for its thievery?
