A solid foundation for their development was the Treaty on Good Neighborliness, Friendship and Cooperation, concluded on July 16, 2001, ”Denisov was quoted as saying by TASS.

He noted that "this historic document, based on the generally recognized norms of international law, has become the starting point for the formation of a Russian-Chinese strategic tandem."

“It allowed Russia and China to reach the highest ever level of relations of comprehensive interaction and strategic partnership in a new era,” the diplomat added.

Earlier, Russian President Vladimir Putin and Chinese leader Xi Jinping officially announced the extension of the Russian-Chinese treaty on good-neighborliness, friendship and cooperation during a video conference.
