(CNN) A year into Donald Trump's presidency, global confidence in US leadership has fallen to a new low, according to an opinion survey conducted across 134 countries.

The Gallup poll puts global approval of US leadership at just 30%, slightly behind China on 31% and only three points ahead of Russia. Germany is now the top-rated global power in the world, with an approval rating of 41%, according to the survey.

The US rating is down nearly 20 points from the 48% approval rating in the last year of President Barack Obama's administration, Gallup said. It's also four points lower than the previous low of 34%, seen in the final year of George W. Bush's presidency.

By comparison, in Obama's last year in office the United States led Germany by seven points, China by 17 points and Russia by 22 points, according to Gallup.

"This year marks a significant change in our trends," said Jon Clifton, global managing partner at Gallup. "Only 30% of the world, on average, approves of the job performance of the US's leadership, down from 48% in 2016.
