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 summit is set to begin at around 13:00 (11:00 GMT). The meeting will be held in a villa overlooking Lake Geneva.
However, there is little prospect that Wednesday's summit will match that meeting either for personal rapport or political thaw.
