Mainland Chinese are mad and they aren't going to take it anymore. Invigorated with new-found wealth (largest foreign exchange reserves in the world since 2006, per capita income up by a CAGR of 11% over the last half a decade, largest carbon polluter in the world, world's 3rd largest economy, etc.), the Chinese are responding as best they can to what they perceive as perfidious foreigners trying to break apart their historic Union (Taiwanese and Tibetan separatists).
For example, I received a chain e-mail from Chinese friends about Tibet, the French and Carrefour (a large, French supermarket chain that has expanded aggressively into Asia and China over the last decade and a half). It calls for a boycott of Carrefour:
May 8th - 24th is exactly three months prior to the Beijing Olympics. Please do not go to Carrefour to shop / purchase. Because: 1. Carrefour's largest shareholder has given money to the Dali Lama. 2. France supports Tibetan Independence severally. 3. The French President declared a boycott of the Oympics. Now, therefore, let us boycott Carrefour for a bit. For a period of time as long as that of the Olympics themselves. For these 17 days, make them see the strength of the Chinese people. Please forward this.
(Point 3 refers to President Sarkozy's demand that China open talks with the Dalai Lama, etc. as a condition for Sarkozy to attend the Opening Ceremony.)
China now has the world's second largest Internet population and we will see Chinese netizens being increasingly proactive in using the Web to further their agendas.
