"There is no end for our cooperation," Xi said. "The two countries should... deepen political and strategic mutual trust, increase mutual support, strengthen strategic coordination, boost practical cooperation, and forge closer people-to-people and cultural links."

Putin echoed Xi saying that the two countries have developed a high-standard relationship with a sound cooperation mechanism, and also, the two heads of state have developed a very good working relationship and a profound friendship.

He said that Xi's visit has achieved a complete success, and the Russian side is willing to work with the Chinese side to continue to strengthen their comprehensive strategic partnership of coordination.

During their talks, the two leaders vowed to abide by the China-Russia Treaty of Good-neighborliness, Friendship and Cooperation no matter how the international landscape changes, bring into play the strategic guiding role of the two heads of state in bilateral relationship, maintain frequent high-level exchanges, and enhance both governmental and non-governmental cooperation.
