Along with other delegations, Mr. Martin travelled overnight by rail from Poland to Kyiv. Strict security was in place.

The topic of sustained military and financial backing for Ukraine is anticipated to be discussed by foreign ministers.

The trip to the city by 27 EU foreign ministers has been a closely kept secret.

The summit takes place at a critical juncture as the pro-Russian candidate Robert Fico's victory in Slovakia's election over the weekend appears to have jeopardised the EU's consensus on financially and militarily helping Ukraine.

In the past, Mr. Fico has backed Vladimir Putin, the president of Russia, and he pledged during the campaign to halt the export of arms to Ukraine.

After winning the election, he declared that his position would not alter.

Additionally, a stopgap financing plan approved by Congress omitted US funding for Ukraine.

Despite this, Kyiv is reportedly hopeful that €500 million in EU military assistance, which Prime Minister Viktor Orban of Hungary has blocked, will soon be given.

The EU also plans to offer 50 billion euros in long-term financial assistance.

Sessions with Ukrainian President Volodymyr Zelensky and Foreign Minister Dymtro Kuleba will be held.

They will talk about Ukraine's entry into the EU and the expense of rebuilding the nation after Russia's invasion.

The Tánaiste will meet with individuals from the Irish community, particularly those engaged in relief efforts, and undertake a series of bilateral discussions.

As he stood next to the EU's top diplomat Josep Borrell, Mr. Kuleba told reporters, "This is a historic event because for the first time ever the foreign affairs council is going to sit down outside of its current borders - outside the borders of the European Union - but within future borders of the European Union."
