US President Donald Trump says Russia should be attending a summit of the G7 group of key industrialised nations.
Arriving at the summit, Trump said he regretted the meeting had shrunk in size - potentially putting him at odds with other members on another issue.
"You know, whether you like it or - and it may not be politically correct - but we have a world to run and in the G7, which used to be the G8 they threw Russia out, they should let Russia come back in," he said.
Kremlin spokesman Dmitriy Peskov responded to Trump's remark, saying that Moscow is "focused on other formats."
The G7 summit, which groups Canada, the US, the UK, France, Italy, Japan and Germany, is being held in the town of La Malbaie in Quebec, Canada.
