UK Reaffirms Support for Ukraine, Emphasizes Ceasefire and Accountability Amid Ongoing Conflict: UK Statement to the OSCE
UK Military Advisor, Lt Col Joby Rimmer, says Ukraine's long-term security depends on a multifaceted approach of immediate ceasefire efforts, robust security arrangements, and economic and humanitarian support.

Thank you, Mr Chair. As we reaffirm our unwavering support for Ukraine in defending its territorial integrity and right to exist, we continue to emphasise the importance of its freedom, sovereignty, and independence. These principles are critical to securing Ukraine’s long-term prosperity and security and are paramount to ensuring stability and peace in the region.
Recent efforts to achieve a ceasefire have rightly dominated the strategic narrative. The meeting on March 11 between the USA and Ukraine in the Kingdom of Saudi Arabia was promising. We applaud Ukraine’s commitment to an immediate ceasefire, which is an essential step towards a comprehensive, just, and lasting peace in line with the Charter of the United Nations. A ceasefire is not only a cessation of hostilities but also a foundation for rebuilding trust and fostering long-term stability.
Although we don’t have the full details from the dialogue between the USA and Russia yesterday, we understand that Putin has repeated his ‘Yes but No’ approach to a ceasefire, expressing concerns regarding the monitoring of the line of conflict and Ukraine’s ability to mobilise and re-arm in the interim. Russia’s demand for the complete cessation of provision of foreign military aid and intelligence to Kyiv is likely to prevent rapid progress. We repeat that any ceasefire must be respected, and that robust and credible security arrangements are necessary to ensure that Ukraine can deter and defend against any renewed acts of aggression.
The UK welcomes the proposed agreement on a cessation of kinetic strikes on energy infrastructure, but again, we call on Russia to fully reciprocate by explicitly agreeing to a ceasefire in all areas and implementing it completely. Should Russia fail to agree to such a ceasefire, we remain prepared to impose further costs, including additional sanctions, caps on oil prices, and increased support for Ukraine. The use of extraordinary revenues stemming from immobilised Russian Sovereign Assets will also be considered.
The devastating impact of the war continues. Russian attacks on civilians and civilian infrastructure are deeply alarming. The destruction of homes, schools, hospitals, and other critical infrastructure has caused immense suffering and displacement. A Russian attack on Pokrovsk on March 17 severely injured three children. A Russian drone attack on a hospital in Kharkiv Oblast caused a 1500 square yard building fire, and the subsequent assault targeted rescue workers. On March 8, a coordinated strike on apartment buildings in Dobropillia killed 11 people and injured 30. We must emphasise the importance of accountability for these actions and reaffirm our commitment again to work together to achieve a durable peace.
In conclusion, Ukraine’s long-term prosperity and security depend on a multifaceted approach that includes immediate ceasefire efforts, robust security arrangements, economic and humanitarian support, and accountability for actions taken during the conflict. By standing together with Ukraine, we can achieve a durable peace and ensure that Ukraine remains democratic, free, strong and prosperous. The path to peace and prosperity is challenging, but it is achievable. Thank you, Mr Chair.
