Russia and China jointly support multi-polarization of the world, safeguard international law as well as the purposes and principles of the UN Charter, and promote the formation of a new international order based on the principles of equality, mutual benefit and win-win cooperation, he said.

In his speech at the gathering, Xi said the two countries are embracing yet another historic moment in bilateral relations.

The past 70 years have fully proved that China and Russia are good neighbors and true partners, as they were before and will be in the future, Xi said.

The two countries will always cherish their unbreakable bond forged with lives and blood during the Soviet Union's Great Patriotic War and the Chinese People's War of Resistance against Japanese Aggression, in which the army and people of the two countries fought side by side against fascism, Xi said.

Just one day after the founding of the People's Republic of China, the Soviet Union recognized the country and set up diplomatic relations with it, Xi recalled, noting that many Soviet experts helped new China lay its industrial foundation.
