From The Economist, November 19th 2020 edition, “Joe Biden’s China policy will be a mix of Trump’s and Obama’s” we read:
Early in his campaign for the presidency, Joe Biden rejected the notion that China was much of a worry. He argued that no leader in the world would trade the challenges facing China for their own.“China’s going to eat our lunch? Come on, man,” Mr Biden scoffed. “I mean, you know, they’re not bad folks, folks. But guess what? They’re not competition for us.” He was speaking in May 2019. Tempered by his contest with Donald Trump, who tried to rally support by highlighting the threat posed by China, Mr Biden now avoids such words.
What does it mean (the text in bold)?
