"Nobody promised anything to each other," he said.
"The possibility of establishing such a group was really discussed. Whether it will be established or not, time will tell, but the heads of state spoke about the possibility… The [Russian] president gave the necessary assurances and clarifications to President [Donald] Trump that any statements about alleged involvement of some official Russian institutions in cyberattacks during the US election campaign are pure fiction," Peskov said.
On Sunday, Trump said on Twitter that he was not sure, whether the joint US-Russian cybersecurity group he discussed with Putin might really be set up.
The first meeting between the Russian and the US presidents, Vladimir Putin and Donald Trump, took place on Friday in Hamburg on the sidelines of the G-20 summit, lasting more than two hours. US Secretary of State Rex Tillerson said at the end of the meeting that the two countries would create a working group to develop a framework agreement on cybersecurity and non-interference in each other's affairs.
