President Trump said Russia, China and Iran may discuss "de-escalation" during upcoming nuclear talks in Beijing and suggested he might engage with North Korea on denuclearization.

President Trump said he 'hopes' Russia agrees to a ceasefire deal after Ukraine accepted the terms earlier this week and warned it would be a "very disappointing moment for the world" otherwise.

Russian President Putin says he agrees in "principle" with President Trump's desire for a 30-day ceasefire but argued it would only help Ukraine and said he wants a lasting peace plan.

Polish President Duda has once again called on the US to place its nuclear arms within its borders to better deter Russia, mirroring talks with France amid security concerns.
