US President Joe Biden and his Russian counterpart Vladimir Putin are preparing sit down for their first, highly-anticipated summit.
The talks in Geneva, Switzerland, come at a time when both sides describe relations as being at rock bottom.
Issues include arms control, sanctions and US allegations of Russian cyber-attacks and election interference.
No major breakthroughs are expected but there are hopes of finding small areas of agreement.
The arrangements for the meeting have been carefully choreographed, with the Russian president due to arrive first at a grand villa overlooking Lake Geneva where the summit is taking place, followed by Mr Biden.
