BEIJING -- President Xi Jinping Friday held talks with his Russian counterpart Vladimir Putin on the sidelines of the Second Belt and Road Forum for International Cooperation in Beijing.

Xi said the relationship between China and Russia has become a major-country relationship featuring the highest degree of mutual trust, the highest level of coordination and the highest strategic value since the two countries established diplomatic ties 70 years ago.

"We should always regard each other as important development opportunities, support each other and draw on each other's strength to achieve revitalization together," he said.

Stressing that Russia is an important partner in the joint development of the Belt and Road Initiative, Xi said the alignment of the BRI with the Eurasian Economic Union is a model of regional economic cooperation.

The two sides should continue to promote cooperation in economy and trade, energy, science and technology, aerospace, connectivity, as well as cooperation at sub-national level and people-to-people and cultural exchanges, Xi said, adding that China will send a pair of giant pandas to Russia for joint research.

Xi also noted that China and Russia should enhance coordination in international affairs, jointly defend the authority of the United Nations and the UN Security Council, uphold the international law and universally recognized norms governing international relations, firmly promote multi-polarity and democracy of international relations, and uphold multilateralism.
