Peskov's comments come a day after Trump called for Russian Federation to be readmitted to the group of the world's leading nations, known as the G7, a step that would end Russia's worldwide isolation over its 2014 annexation of Crimea from Ukraine.
Mr Xi told media after their meeting that both he and his Russian counterpart felt "the China-Russia comprehensive strategic partnership is mature, firm and stable". Trump said at the White House just before departing.
But all the leaders did endorse Mr. Trump's historic denuclearization talks with North Korean leader Kim Jong-un in Singapore next week.

Russian Federation has never turned its back on the G8 (now G7), Vladimir Putin said, speaking at the Shanghai Cooperation Organisation (SCO).

Tensions mounted between the Trump administration and fellow G7 members Canada, Germany and France when the U.S. imposed steep tariffs on imported metals from the countries.
