Xi expressed his sympathy for the heavy casualties and property losses in Japan's Kansai area and Hokkaido, which were hit not long ago by a powerful typhoon and an quake respectively.
"In a rapidly changing worldwide situation with growing instability and unpredictability, cooperation between Russian Federation and China takes on even more importance", said Xi, according to a transcript on the Kremlin's website.
Putin said this would "increase the stability of banks' servicing of export and import operations while there are ongoing risks on global markets". "And then we will continue to address all controversial issues as friends based on the peace treaty", the president went on.
Pancake making seems to be a way of bonding for Russian President Vladimir Putin and Chinese premier Xi Jinping.

Russian Federation is getting closer to concluding a deal on a new route for transporting gas to China, its energy minister said on Wednesday.
For his part, Abe appreciated Xi for his sympathy for Japan's losses caused by the natural disasters.
Lee Nak-yeon, in his turn, thanked the Russian leader for cooperation and initiatives in solving worldwide issues, including denuclearization of the Korean Peninsula.
Japanese businesses have also voiced desire for closer ties with China to boost trade. On Monday, Japan's Prime Minister Abe said he was ready to provide financial aid to Pyongyang on condition that it resolves the issues of its nuclear and missile tests and abducted Japanese nationals. But he had said earlier that the lack of a peace treaty was "an abnormal state of affairs".
