(CNN) President Donald Trump on Saturday doubled down on his call for Russia to be readmitted into the G7 and blamed his predecessor for Russia's aggression in Crimea.

"I think it would be an asset to have Russia back in," Trump said during an impromptu press conference at the summit. "I think it would be good for the world. I think it would be good for Russia. I think it would be good the United States. I think it would be good for all of the countries of the current G7. I think the G8 would be better."

Russia was suspended from the group -- then known as the G8 -- in 2014 after the majority of member countries allied against its annexation of Crimea. It was the first violation of a European country's borders since World War II.

Trump suggested that Russia be allowed back into the global group despite their continued occupation of Crimea.
