The Chinese public has increasingly expressed reservations about relations U.S.-Chinese relations, a Pew Research Center poll of 3,177 adults in China found.
Just 39 percent of respondents said they believe China's relationship with the United States is one of cooperation while 68 percent felt that way in 2010.
Similarly, while 58 percent of respondents said they had a positive view of the United States in 2010, only 43 percent said the same in the most recent poll, the Pew Research Center said.
President Barack Obama's ratings also have dropped among residents of China, from 52 percent expressing confidence in him in 2010 to 38 percent saying that now.
However, 52 percent of Chinese said they like American ideas about democracy.
The Pew Research Center conducted the poll March 18-April 15. The poll has a margin of error of 4.3 percentage points.
