Russia aims to occupy all Ukrainian territory east of the Dnipro River and advance toward Odesa and Mykolaiv in a broader plan to sever Ukraine's access to the Black Sea, President Volodymyr Zelensky's Deputy Chief of Staff Pavlo Palisa said, Politico reported on June 6.
The remarks come amid continuing Russian offensives in eastern and northern Ukraine, along with escalating diplomatic efforts that have yet to yield a ceasefire.
According to Ukraine's military intelligence agency (HUR), Moscow hopes to seize the entirety of Donetsk and Luhansk oblasts by this fall and establish a buffer zone along Ukraine's northern border with Russia.
The second phase of the plan envisions more ambitious territorial gains, including an advance into southern Ukraine aimed at cutting the country off from the sea.
"Unfortunately, they are not speaking about peace. They are preparing for war," Palisa said during a press briefing at the Ukrainian Embassy in Washington.
The warning comes days after Russia presented Ukraine with a so-called "peace memorandum" during a second round of negotiations in Istanbul on June 2.
The document, published by Russian state media outlet TASS, demands that Kyiv recognize Russia's claimed annexation of four Ukrainian oblasts — Kherson, Donetsk, Zaporizhzhia, and Luhansk — and fully withdraw from them.
Moscow also calls for Ukraine's demobilization and a formal ban on NATO membership.
During the talks, Ukraine's delegation submitted a separate proposal calling for an all-for-all prisoner exchange, the return of abducted Ukrainian children, and the release of civilians held in Russian captivity.
Kyiv also reiterated its call for a Western-backed 30-day ceasefire as a foundation for future negotiations — a proposal Moscow again rejected.
Ukraine's military leadership has warned that Russian forces are preparing for a major summer offensive in Donetsk Oblast, where daily assaults have continued since 2022.
Despite suffering heavy losses, Russian troops are advancing through mass wave attacks that gain only tens of meters per day. According to the U.S.-based Center for Strategic and International Studies (CSIS), Moscow currently occupies roughly 20% of Ukraine.
