WASHINGTON - China has either replaced or will replace the United States as the world's leading superpower, according to a new poll conducted by Pew Research Centre, which notes that anti-Americanism is growing around the world. In 15 of 22 nations, including Pakistan, the poll found that the US image now faces a new challenge: doubts about Americas superpower status. This view is especially widespread in Western Europe, where at least six-in-ten in France (72%), Spain (67%), Britain (65%) and Germany (61%) see China overtaking the US Majorities in Pakistan, the Palestinian territories, Mexico and China itself also foresee China supplanting the US as the worlds dominant power. In most countries for which there are trends, the view that China will overtake the US has increased substantially over the past two years, including by 10 or more percentage points in Spain, France, Pakistan, Britain, Jordan, Israel, Poland and Germany. Among Americans, the percentage saying that China will eventually overshadow or has already overshadowed the US has increased from 33% in 2009 to 46% in 2011. At least some of this changed view of the global balance of power may reflect the fact that the US is increasingly seen as trailing China economically. This is especially the case in Western Europe, where the percentage naming China as the top economic power has increased by double digits in Spain, Germany, Britain and France since 2009. In other parts of the globe, fewer are convinced that China is the worlds leading economic power. Majorities or pluralities in Eastern Europe, Asia, and Latin America still name the US as the worlds dominant economic power.
