Chinese President Xi Jinping told his Russian counterpart Vladimir Putin in a call Wednesday that Beijing would keep backing Moscow on "sovereignty and security", according to state media.
China is "willing to continue to support (Russia) on issues concerning core interests and major concerns such as sovereignty and security," Chinese state broadcaster CCTV reported Xi as saying.
It was the second reported call between the two leaders since Putin launched his invasion of Ukraine on February 24.
China has refused to condemn Moscow's invasion of Ukraine and has been accused of providing diplomatic cover for Russia by blasting Western sanctions and arms sales to Kyiv.
According to CCTV, Xi praised the "good momentum of development" in bilateral relations since the start of the year "in the face of global turmoil and changes".
Beijing was willing to "intensify strategic coordination between the two countries", Xi reportedly said.
China was ready to "strengthen communication and coordination" with Russia in international organisations and "push the international order and global governance towards more just and reasonable development," he added.
Xi also met Putin in person on the eve of the Beijing Winter Olympics in February.
