US President Donald Trump has said getting on with Russia is “a good thing, not a bad thing” at the start of his first summit with Vladimir Putin.
Mr Trump said he hoped for an “extraordinary relationship” as the two presidents met in Helsinki, Finland.
Earlier Mr Trump denounced his predecessors’ “stupidity” for tensions.
US-Russia relations have been strained by Moscow’s annexation of Crimea in 2014 and by claims that the Kremlin helped Mr Trump win the 2016 election.
Some US politicians had called for the summit to be cancelled after 12 Russian military intelligence agents were charged on Friday with hacking the presidential campaign of Democratic candidate Hillary Clinton.
But in his tweet, Mr Trump put the blame for the deterioration in relations with Russia on “years of US foolishness and stupidity and now, the Rigged Witch Hunt”.
In response, Russia’s foreign affairs ministry tweeted: “We agree.”
BBC diplomatic correspondent James Robbins says Mr Trump’s tweet is likely to alarm White House advisers, already nervous about the risks of giving too much ground to the Russian leader during the talks.
Many in the West have criticised Moscow for what they regard as its destabilising activities in Ukraine. The US, among others, has imposed sanctions on Russia over its annexation of Crimea.
The summit – in which the two leaders are being joined only by their interpreters – comes after a tumultuous European tour that saw Mr Trump criticise allies of the US over trade and military spending.
