US Secretary of State Antony Blinken is due to visit Ukraine’s capital Kyiv later today, accompanied by US Defence Secretary Lloyd Austin.
The pair will meet Ukraine’s President Volodymyr Zelenskyy to talk about the country’s request for more weapons to repel the Russian invasion.
Mr Zelenskyy announced the visit on Saturday, saying: "I believe that we will be able to get agreements from the United States or part of that package on arming Ukraine which we agreed on earlier.
"Besides, we have strategic questions about security guarantees, which it is time to discuss in detail, because the United States will be one of those leaders of security countries for our state.
"As soon as we have (more weapons), as soon as there are enough of them, believe me, we will immediately retake this or that territory, which is temporarily occupied."

It comes as the war in Ukraine enters its third month with no end in sight, many thousands of people dead, millions having become refugees, and cities reduced to rubble.
Meanwhile, a three-month-old baby girl was among eight people killed after Russia fired cruise missiles at the Black Sea port city of Odesa, according to Ukrainian officials.
Speaking about the casualties, Mr Zelenskyy said: "The war started when this baby was one-month-old. Can you imagine what is happening?
"They are just b********…I don’t have any other word for it – just b*******."
The baby’s mother and grandmother were also killed, and 18 people were injured, according to reports.
Also, UK Prime Minister Boris Johnson spoke to Mr Zelenskyy on Saturday and confirmed Britain would supply new weapons to support Ukraine.
A read-out of the call published by No 10 said: "The prime minister confirmed that the UK is providing more defensive military aid, including protected mobility vehicles, drones and anti-tank weapons."
