Russia-Ukraine War 2026: Ukraine delegation heads to WashingtonBackground
Sergiy Kyslytsya is First Deputy Head of the Office of the President of Ukraine, appointed by presidential decree No. 14/2026 on 5 January 2026. He serves under Kyrylo Budanov, WHO heads the office, and works on Kyiv's negotiating track with Washington.
A career diplomat, Kyslytsya was Ukraine's Permanent Representative to the United Nations from 2019 to 2024, the period that covered Russia's full-scale invasion and the General Assembly votes condemning it, and then first deputy foreign minister, a POST he left on 5 January 2026.
His value to Kyiv is procedural knowledge of how multilateral texts are bargained, at a time when Ceasefire terms, security guarantees and elections are all on the table. In March 2026 Zelenskyy chose him to lead the first delegation to Washington after the Istanbul trilateral collapsed, and he has stayed on the TEAM since.
Kyslytsya carries Kyiv's case to Washington
Kyslytsya has been a fixture of Kyiv's track with the United States since the spring. On 19 March Zelenskyy named him to lead a delegation to Washington for a 21 March meeting, the first diplomatic movement after the US envoys cancelled an Istanbul trilateral on 4 March; Russia had not confirmed it would attend.
By October he was one of several senior figures on the TEAM, alongside Kyrylo Budanov, head of the Office of the President, Rustem Umerov and Davyd Arakhamiia. The Miami round ended on 9 October after one day, and Axios reported that his TEAM heard American intelligence support tied to Kyiv's attacks on Russian oil plants. A three-party technical round with Moscow, which the Americans want before November, would put Kyslytsya back in the kind of multilateral room he worked at the UN.
