Today, US President Joe Biden and his Chinese counterpart President Xi Jinping are having their first face-to-face meeting since Joe Biden was elected in 2020. Since they last met in 2011, when both were vice presidents, tensions between Washington and Beijing have only escalated. Stabilizing the world’s most important bilateral relationship is essential to China, the US, and the rest of the world. Checks and balances limit Biden's executive powers to deal with Xi’s China. The same can't be said for President Xi.
