Andrii Yermak, Head of the Office of the President of Ukraine, has said that the security agreement with the US will be different from, and more comprehensive than, Ukraine’s security agreement with the UK.

"I think that the [security] agreement with the US will have more [clauses]. I think it will be even more special. We’re working on it," Yermak said in an interview with Interfax-Ukraine news agency.

When asked why Ukraine concluded its first security agreement with the UK and not the US, Yermak said that this was an "internal agreement". 

"With the US, we’re preparing for it, we’ve already started the first rounds of consultations. The US remains our main partner and ally, as before," Yermak stressed.

In July 2023, the G7 leaders, together with Ukraine, agreed on a framework for security guarantees, though they did not agree on specific criteria; specific bilateral agreements would be signed later with individual countries.

In January 2024, Ukrainian President Volodymyr Zelenskyy and UK Prime Minister Rishi Sunak signed a bilateral security agreement, which will remain in force until Ukraine joins NATO. This is the first bilateral agreement concluded following the Vilnius NATO summit between Ukraine, members of the G7, and the states that joined them.
