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.
Under plans agreed by the UK, US, France, Germany, Canada, Italy and Japan, there will be greater co-ordination to respond to threats including cyber attacks and other breaches of global rules.
"Looking forward to straightening out unfair Trade Deals with the G-7 countries".
Russian Federation has never turned its back on the G8 (now G7), Vladimir Putin said, speaking at the Shanghai Cooperation Organisation (SCO).
Russian Federation joined the group in the 1990s after emerging from the wreckage of the Soviet Union, making it the G-8, but its armed intervention in its neighbor Ukraine in 2014 and seizure of the Crimean peninsula angered other major powers. "If it doesn't happen, we come out even better!" the president wrote on Twitter, hours before he's due to arrive in Quebec.More news: Flight from Pyongyang lands in Singapore ahead of North Korean leader’s arrival
In May, the president announced his administration would impose steel and aluminum tariffs on Canada, Mexico and the European Union - all of which announced retaliatory tariffs against the U.S.in recent days. Trump tweeted Friday. "Canada charges the USA a 270% tariff on Dairy Products!"
Velshi picked up on the "you're not more important to me because you're an ally" aspect of what Trump is doing on trade.
In Italy, meanwhile, a spokesman for the new populist government that has signaled a similarly conciliatory approach toward Moscow said Rome agrees with Trump's call. 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. Canada has countered with a plan to impose tariffs of its own on US metals and other consumer goods.
He has called Trump's imposition of the tariffs "irresponsible" and "insulting" because the two countries have fought as allies in Second World War, Korea and Afghanistan.
The French and Canadian leaders have each vowed to address the tariffs with Trump at the summit.
Lavrov said on national television that Russian Federation "never asked anyone to return" to the Group of Seven following the 2014 decision to suspend Russian Federation over Moscow's annexation of Crimea.
But Kudlow was quick to downplay the rift between the president and United States allies.
