This kinda looks like a bad poll. The wording seems to setup a bad choice of extremes. The respondent has to either choose "friendly" or "an enemy". But the relationship between the US and China is a much more complex thing. The US and China are certainly in competition in a number of areas, economically and geopolitically. The induction of China to the WTO in 2001 impacted the US's manufacturing sector negatively (see: https://www.bls.gov/opub/btn/volume-9/forty-years-of-falling-manufacturing-employment.htm). The US and China are at odds over the fate of Taiwan. But, in spite of all that, the US and China have deep trade links which benefit both countries greatly. And both countries are likely better off than they would be without the other. Global trade is generally positive for the economies involved, though global trade can also fuck individuals inside each economy, including driving wealth concentration and harming the economically disadvantaged and people whose skills don't align well with the industries their country is focused on.

Trying to boil US-China relations down to either Friendly or "Enemy" misses a lot of the nuance and may mean people aren't giving an accurate picture of how they view China.
