KYIV, Ukraine >> Fresh off securing a plan to receive more U.S. weaponry, Ukrainian President Volodymyr Zelenskyy has appointed a new prime minister — the key negotiator of his country’s deal with the U.S. to partner on the development of minerals.

By naming Yulia Svyrydenko, the former economy minister, to become the country’s first new head of government since Russia’s full-scale invasion in 2022, Zelenskyy on Thursday elevated a loyal politician who has experience in diplomacy with the U.S. and other Western nations.

In addition to negotiating the mineral agreement — seen as an important way of tying U.S. interests to Ukraine’s security — Svyrydenko, 39, has represented her country in a wide range of high-level talks with Western partners, including on issues of defense and economic recovery and reconstruction. In 2022, she negotiated with other countries to impose sanctions on Russia.

The outgoing prime minister, Denys Shmyhal, will become defense minister at a time when Ukraine is looking to ramp up domestic weapons production, and as President Donald Trump seeks to bring an end to the war.

Svyrydenko and Shmyhal are among a wider group of officials taking on new leadership roles as Zelenskyy aims to reenergize a war-weary nation. But to Ukrainians, the reshuffling of the Cabinet is not seen as a major shift in direction for Zelenskyy.
