The summit between Russian President Vladimir Putin and US President Donald Trump will take place in Helsinki on 16 July, the Kremlin and the White House say.

The Kremlin said the two leaders would discuss the current state and outlook for US-Russia relations as well as international issues

Moscow and Washington struck a deal on Wednesday to hold the summit, a move likely to worry some US allies and draw a fiery reaction from some of Trump's critics at home.

US-Russian relations have plummeted in recent years amid Russia's involvement in the Ukraine crisis and allegations that Russia meddled in the 2016 US presidential election.

Trump on Wednesday listed Syria and Ukraine among the many subjects he said they would discuss. His list did not include warnings from US intelligence officials that Russia will try to interfere in US congressional elections in November.

The two men last met in November on the sidelines of an Asia-Pacific summit in Vietnam. After those talks, Trump said he believed Putin's denials Russia had meddled in the 2016 US election - remarks Trump later backed away from.
