Asked at the Valdai Discussion Club in Moscow to comment on controversial plans by the White House to invite Putin to the USA this fall, Anatoly Antonov said: "The Russian side has always been open to possible proposals".
In reaction to Putin's proposal, the howls of protest came fast and furious.
Hurd adds that Trump's initial failure to support the US intelligence community's assessment that Russian Federation interfered in the 2016 elections should concern all Americans. In exchange, U.S. Special Counsel Robert Mueller could send members of his team to watch Russian questioning of 12 Russian intelligence agents indicted by a U.S. grand jury last week in connection with hacking Democratic Party email accounts before the 2016 election.
The US citizens Russia would like to question are related to Moscow's case against the financier Bill Browder, a fierce Putin critic who was instrumental in the US imposing sanctions in 2012 on top Russian officials accused of corruption.
Sanders said Putin's proposal was "made in sincerity", but Trump "disagrees with it". Trump was "grudgingly convinced" by the material, according to several people who were in the intelligence briefing, the New York Times stated.
Democrats are also calling on the Trump administration to provide information on any promises Trump might have made to Putin during their meeting.
"The Summit with Russian Federation was a great success, except with the real enemy of the people, the Fake News Media", he twittered on Thursday.
Andrei Kostin, head of the state-run bank, VTB, said the "spirit" of the summit created grounds for further cooperation between the two countries. One of the most vocal opponents was Michael McFaul, who served as United States ambassador to Russian Federation from 2012 to 2014 under the Obama administration. In a story explaining the cover, the editors said the merged image represents the conflict between the question of alleged collusion with Russian Federation and the question of whether Russian Federation attempted to influence the 2016 presidential election.
The Russian ambassador to Washington also denounced "anti-Russian anger" in the United States and reiterated denials of Russian meddling in the 2016 presidential election - interrupting a questioner to say "We didn't interfere!"
After Helsinki, Trump plans to host Putin in Washington
Antonov gave details of their discussions on arms control, but said the US has been reluctant to back Russia's proposals so far. She said the administration is working to make sure Russian Federation doesn't meddle in the 2018 midterm elections.
His comments came on the heels of a New York Times report that said Trump, two weeks prior to his inauguration, had been presented with extensive evidence that the Russian strongman personally ordered the meddling in the U.S. election.
"We will respond appropriately to such aggressive steps, which pose a direct threat to Russian Federation", said Putin.
"Now, with that being said if that doesn't work out I'll be the worst enemy he's ever had - the worst he's ever had", he added.
'Say that again? Did I hear you?' he said upon learning the news, which White House press secretary Sarah Sanders announced on Twitter.
But a day later, Trump said he misspoke during the summit.
He has called the summit "a great success", but he has been vague about what he discussed with Mr Putin. Among the long list of issues he said he and Putin had spoken about: terrorism, nuclear proliferation, "cyber attacks", trade, Ukraine, Israeli security and Middle East peace, and North Korea.
