Over the years, China and Russia have described their relationship as a friendship without limits. Vladimir Putin's visit to Beijing this week further emphasises the strength of those ties. He and President Xi Jinping hailed their partnership as 'a force of calm among chaos'. They also warned against a return to the 'law of the jungle'. An apparent reference to Donald Trump's actions and policies, which include the war against Iran and sweeping global tariffs. Will the two leaders succeed in their push for a multipolar world, one in which the U.S. does not dominate?
