People the world over tend to believe that China will surpass the US to become the world's leading superpower, China News Service said, citing a global survey.

Conducted by the Pew Research Center, the survey of 48,643 respondents older than 18 in 44 countries found that 49 percent agree that China will eventually replace or has replaced the US as the world's leading superpower, while 34 percent disagree.

This view is shared across all regions surveyed, especially among European countries. Across the seven European Union nations polled, 60 percent think China will or already has replaced the US.

In general, global views of China are positive. China's growing economy is considered a good thing by most countries, though China's increasing prosperity is considered a threat in some, one of which is the US.

China's image in the US has deteriorated, with 35 percent expressing a positive view, down from half in 2011, the report said.

Meanwhile, the rising power of China is generating anxiety among its neighbors. More than half of respondents in 11 Asian countries surveyed worry that territorial disputes will lead to conflict with China, including 93 percent of Filipinos, 85 percent of Japanese, 84 percent of Vietnamese and 83 percent of South Koreans.

Two-thirds of Americans and 62 percent of Chinese also say they are concerned.

Respondents in Japan, the Philippines and Vietnam see China as their top security threat, while the US is seen as the top security threat in three Asian nations: China, Pakistan and Malaysia.

Across the globe, young people tend to have more positive attitudes toward China than older respondents. In 23 countries, people aged 18 to 29 give China higher ratings than those 50 and older. In the UK, Mexico, the US and France, the gap between older and younger respondents is 20 percentage points.
