In his nightly video address, Ukrainian President Volodymyr Zelenskyy said he did expect his officials to meet the US negotiators again after they spoke on Sunday — before the talks with Moscow.

While Zelenskyy did not specify when this would happen, Ukraine’s national broadcaster Suspilne cited a source in the Ukrainian delegation saying it would be on Tuesday.

A member of Ukraine’s delegation told AFP news agency on condition of anonymity that Ukrainian and US officials were holding a round of talks Tuesday in Riyadh.  

At a previous round of talks this month in Jeddah, Kyiv agreed to a US-proposed 30-day truce that Russian President Vladimir Putin subsequently rejected.

Officials are now studying a possible resumption of the Black Sea Initiative, an agreement that allowed millions of metric tons of grain and other food exports to be shipped from Ukraine’s ports.
