NEW YORK - China and the United States needed to further improve political and business cooperation, according to a new survey released on Thursday.

The survey, conducted by the Committee of 100 (C-100), a US non-partisan Chinese-American cultural-exchange advocacy organization, revealed that less than half of the US public (48 percent) think the US should trust China a great deal or some, while among Chinese participants, 45.8 percent think the US is trustworthy.

Titled "US-China Public Perceptions Opinion Survey 2012", the survey also found that the US public's top two concerns of China are the alleged loss of US jobs to China (40 percent) and the US trade deficit with China (35 percent) , while the US-China dispute over the Chinese currency exchange rate is the top most concern of the Chinese public.

"We will use this study to advocate for constructive relationship-building between the peoples of the US and China and to further promote education, diplomacy, and leadership development," said Dominic Ng, C-100 Chairman.

The study surveyed 1,400 Americans and more than 4,000 Chinese people from December 14, 2011 to January 31, 2012, which measures significant shifts in US and Chinese attitudes since 2007 on high-impact economic, political, and security issues, including trade and investment, and US military presence in the Asia Pacific.
