The UK Prime Minister will push allies to supply Ukrainian forces with additional long-range missiles to strike Moscow's positions during talks in Britain on this Friday.
Britain's leader is set to welcome President the Ukrainian head of state alongside what's known as "coalition of the willing", comprising numerous of Kyiv's partners who have committed to provide Ukraine security guarantees once hostilities pause is arranged.
Ukraine's president has been pleading for several weeks for more long-range weapons from Western nations, a move that Moscow has warned would worsen the conflict.
President Zelensky is journeying from the EU capital, where he held talks with European Union officials on Thursday seeking funding aid.
"The only person participating in this conflict who does not want to end the war is President Putin," Sir Keir said.
Britain's leader will also declare that one hundred extra anti-aircraft missiles will be provided to Kyiv earlier than planned, as specified in a £1.6bn deal struck between the UK and Kyiv in last spring.
Ukraine's leader comes following significant diplomatic successes recently: Washington's action to implement additional restrictions against Moscow, and EU nations deciding to fund Kyiv's budgetary shortfall.
Britain's leader is seeking to maintain the forward movement by intensifying the pressure on Russia to discuss an end to the conflict.
Sir Keir will press leaders to increase the supply of advanced missile technology following an effective operation on a manufacturing site in the Russian city, the Russian Federation, using Britain-delivered advanced weaponry.
"And his brutal assaults on small children in a daycare recently demonstrate that perfectly obvious," he continued.
Several minors were included in at least seven fatally wounded in multiple Russian strikes on Ukraine, which targeted a nursery in the important metropolitan area the eastern city.
Sir Keir will confer with partner nations on approaches for remove Moscow's energy exports off the global market.
Delegates will also consider using blocked Russian resources to offer the Ukrainian government with monetary support, though the plan encountered insufficient agreement and legal hurdles at the Brussels summit on the previous day.
The EU opted against consenting to a proposal to employ as much as €140 billion in frozen Russian assets to economically support the Ukrainian economy.
However, the participants agreed to help support Ukraine's "economic requirements" for the coming 24 months.
The US also disclosed restrictions on recently against the Russian biggest petroleum firms, the state-owned company and the private firm, as component of initiatives to add economic pressure on the Kremlin to commence hostility discussions.
Moscow began its comprehensive attack of the country in winter 2022. Russian troops at this time holds about 20% of the country's land, encompassing the southern Crimea peninsular Moscow seized in several years ago.
