We will continue our steadfast support for Ukraine on its path to join the Alliance as soon as possible. Ukraine has proven its readiness to further our shared principles of democracy, individual liberty, and the rule of law, as well as to contribute to the security of the North Atlantic area," the prime ministers said in the statement.

They also expressed their readiness to work closely with Ukraine on its way to EU membership.

"Following the evaluation of the fulfilment of the recommendations, we look forward to the start of accession negotiations in 2023. A strong, independent and prosperous Ukraine that is fully anchored in the Euro-Atlantic family is essential for European security. With this in mind, we join the G7 Declaration of Support for Ukraine. We will work with Ukraine within this multilateral framework to establish security commitments and arrangements that would help Ukraine win this was as soon as possible, support its economic stability and reconstruction, resilience, reform agenda and advance its European and Euro-Atlantic aspirations," the document says.

"We have stood together with Ukraine since day one of Russia's unprovoked and brutal aggression. We will keep supporting Ukraine until victory and continue contributing to international efforts to safeguard its independence, sovereignty, security, democracy, and prosperity. We will sustain efforts to hold to account all those responsible for the crime of aggression and other international crimes," the prime ministers said.
