The new cold war between the United States and China shows signs of thawing.
The Biden-Xi summit was a sign of progress in relations between the two countries after a period of high tensions, but the roots of the increasingly bitter rivalry remain.
After the leaders of the world’s two superpowers concluded a four-hour meeting in San Francisco, the US president took out his cellphone and showed his Chinese counterpart a photo.
“Do you know this young man?” Joe Biden asked, according to Chinese state media. “Yes,” Xi replied with a smile. “That was 38 years ago.”
