Dmitry Peskov, a Kremlin spokesperson, explained: "President Putin is a supporter of dialogue in all directions, but in this case, in order to respond to such initiatives, we need to receive more information, which we unfortunately do not have.
"We don't know the details of this proposal yet, we don't know if it is official.”
Mr Peskov added the G20 gave Russia a platform to discuss international issue with other countries.

On why he wished to expand the group, Trump explained: “I don't feel that as a G7 it properly represents what's going on in the world.
“It's a very outdated group of countries,”
The other members are Canada, Germany and the United Kingdom.
