US President Donald Trump has tweeted that “it is time to move forward in working constructively with Russia,” citing a ceasefire negotiated for southwest Syria as proof that this is possible.

Donald Trump met with Russian President Vladimir Putin for more than two hours in Hamburg on Friday, the first day of the G20 summit.

“We negotiated a ceasefire in parts of Syria which will save lives. Now it is time to move forward in working constructively with Russia!” Trump wrote on Twitter.

Trump also tweeted that he and Russian President Vladimir Putin had discussed forming an impenetrable cybersecurity unit to prevent election hacking.

Putin confirmed on Saturday that the accusations claiming Russia meddled in the US election had been addressed during his conversation with Trump. The Russian president reiterated that there is no reason to believe that Russia interfered in the US electoral process.

“He [Trump] asked many questions on that subject. I answered those questions as best I could. I think he took it into consideration and agreed with me, but you should really ask him how he feels about it,” Putin said.

Putin confirmed on Saturday that both leaders had shared their views on cybersecurity, saying they had agreed to “create a working group and work together on how to jointly monitor security in cyberspace.”
