Biden has been clear in two phone calls with Putin that he will not "simply elide or gloss over the differences that we have; he's going to take them on with candor and directly, and that where Russian Federation crosses lines that we consider to be unacceptable, we will impose costs on Russian Federation for doing that", the official said.
Biden hopes the denunciation will be part of the joint communique released at the summit's end, but some European allies have been reluctant to so forcefully split with Beijing.
"The needs in the developing world for high-quality infrastructure - whether it's physical infrastructure, digital infrastructure, health infrastructure, or a way to deal with gender disparities - are large and growing, and made especially worse after the pandemic", the official said. But in a statement, the official said there was "a growing convergence" among G7 countries on highlighting China's "human rights abuses, including in Xinjiang".
In a rare interview with U.S. media released Friday, Putin voiced hope that Biden would be less impetuous than Donald Trump, who infamously sided with the Russian leader against the views of his own intelligence chiefs.

The initiative is described as "a values-driven, high-standard, and transparent infrastructure partnership led by major democracies".
The multi-trillion-dollar project was launched by Chinese President Xi Jinping in 2013.

In an interview with USA network NBC News released Friday, Putin voiced hope that Biden would exhibit none of the "impulse-based movements" of Trump, who notoriously sided with the Russian leader against the views of his own intelligence chiefs.
The leaders planned to attend a barbecue Saturday night, complete with toasted marshmallows, hot buttered rum and a performance by a sea shanty troupe.
"A solo press conference is the appropriate format to clearly communicate with the free press the topics that were raised in the meeting - both in terms of areas where we may agree and in areas where we have significant concerns". Only Biden will address the news media after the meeting.
Putin told NBC that US-Russian relations had reached their lowest point in recent years, and while he didn't say it was because of Biden, a Democrat, succeeding Republican Donald Trump as president, he did contrast the two American leaders.
"That's a different kind of person, and it is my great hope that yes, there are some advantages, some disadvantages, but there will not be any impulse-based movements, on behalf of the sitting USA president", he added.More news: Canada to ease restrictions for vaccinated travelers
