China-Russia relations: What is Xi Jinping prepared to pay for Putin’s war?

Beijing is set to welcome Russian President Vladimir Putin, who hailed the "unprecedented" level of ties between the two countries ahead of his state visit.

More than two years into his invasion of Ukraine, China has emerged as a vital ally. It has refused to condemn the war and continues to trade with a heavily sanctioned Russia, much to the ire of the US and the European Union.

However, it appears Mr Putin wants more. But is China willing to pay the price?
