Transatlantic Trends 2006 is a project of the German Marshall Fund of the United States and the Compagnia di San Paolo in Turin, Italy, with additional support from the Fundação Luso-Americana (Portugal), the Fundación BBVA (Spain), and the Tipping Point Foundation (Bulgaria).
To grab just one finding from the press release:
China threatening: When asked to rate their feelings of warmth toward China on a 100-point "thermometer" scale, Americans and Europeans rate China virtually identically (46 degrees to 45 degrees). But 38% of Americans, compared with 27% of Europeans, feel that the rise of China is an "extremely important threat" in the next ten years. In the United States, the largest percentage of respondents is more concerned by the threat posed by growing Chinese military power (35%), while in Europe, the largest percentage of respondents is more concerned by the threat posed by the growing Chinese economy (37%). Among Europeans, the highest perception of the threat of the Chinese economy is in France (53%), Portugal (52%), and Italy (51%). Within the United States, Democrats are more concerned about the economic (37%) than military threat (28%), and Republicans are more concerned about the military (42%) than economic threat (21%).
Considering the fact, that the U.S. has much stronger military ties than Europe with South Korea, Japan and Taiwan, the different perception of China does not come as a surprise. Apart from that, I don't like phone-conducted surveys.
