Xi's decision to talk to Russian college students underscores Beijing's determination to enhance mutual understanding between the youths in both countries, as they will be future players in bilateral relations, said Ji Zhiye, vice-president of the China Institutes of Contemporary International Relations.

Feng Yujun, head of Russian studies at the institutes, said Xi's speech maps out a blueprint for the development of Sino-Russian ties at a time when both countries are experiencing a critical stage of national revival.

"The two countries have been very clear that their revival dream and development can serve as each other's opportunities. With such consensus, China and Russia will definitely keep strengthening strategic and economic coordination," Feng said.

Xi was also invited to Russia's defense headquarters, a first for a top Chinese leader. Experts said the move shows the deep trust China and Russia share, and a strong potential for future military cooperation.

In Moscow, Xi also held talks with Russian Prime Minister Dmitry Medvedev.

After Russia, the president will fly to Africa for visits to Tanzania, South Africa and the Republic of Congo. In South Africa, he will attend the fifth BRICS summit, the first on the African continent. Leaders of the BRICS countries will also meet African leaders in a joint retreat.
