Speaking to the media after a 40-minute meeting with Trump at UN headquarters in New York on Tuesday, Zelenskiy said Kyiv was ready for any format of an energy ceasefire with Moscow, but there had been no discussion of Ukraine unilaterally halting its attacks on Russian oil refineries.
Zelenskiy reiterated that he was ready to meet Russian President Vladimir Putin at a trilateral meeting with Trump, adding that he hoped the US would find a way to bring Moscow back to the negotiating table after talks unravelled earlier this year.
Zelenskiy, however, said he had seen no indication that Putin was ready to talk.
"I'm ready for a trilateral meeting. It means that I'm agreed to end the war," Zelenskiy said.
Moscow stepped up airstrikes over the summer, and has been attacking economic targets ranging from businesses and ports to logistics hubs, with its advances on the ground largely stalled more than four-and-a half years into its war in Ukraine.
"Russia deliberately targets businesses, farms, warehouses, railways, energy facilities and residential buildings," Ukrainian Prime Minister Sergii Koretskyi said on Telegram.
Ukraine has also increased long-range strikes in recent months, targeting Russian oil refineries and big online retailers in an effort to undermine Moscow's war effort.
The Ukrainian military said on Tuesday it had hit a Russian oil refinery in the city of Ufa, more than 1300km from the border with Ukraine. It also said it had struck the Kuibyshev oil refinery in the Samara region on the Volga river.
The Samara region governor said Ukrainian drones hit civilian targets in the region, killing one person and injuring four. Both sides deny targeting civilians.
Trump said last week that Ukraine and Russia had agreed not to strike energy targets, but any semblance of a truce disappeared when Russia hit petrol stations in Kyiv the following day and Ukraine bombed a Russian oil refinery.
Continuing attacks on Ukraine's economic infrastructure, Moscow hit industrial enterprises in the cities of Dnipro, Kryvyi Rih and Pavlohrad in the southeastern region of Dnipropetrovsk, regional governor Oleksandr Hanzha said on Telegram.
The region is home to machine building, steelmaking and other major production.
A Russian missile strike on a facility in Dnipro owned by Interpipe, Ukraine's largest pipe producer, killed four people and wounded seven, the company said.
Prosecutors said Russian attacks on the southern region of Kherson killed two people and the regional governor said one person was killed near the Black Sea port of Odesa.
Police in the eastern Donetsk region, the focal point of much of the frontline fighting, said Russian aerial bombs killed one person in Kramatorsk, one of the "fortress towns" that Russia would like to capture.
A mass airstrike on the town of Izium, in northeastern Kharkiv region, injured seven people, local officials said.
The overnight Russian barrage included an unspecified number of Oniks anti-ship and ballistic missiles, as well as four cruise missiles and 212 drones, Ukraine's air force said.
Russia's defence ministry said its forces hit industrial and military facilities in Ukraine, targeting the fuel and energy sector as well as port infrastructure facilities and sea vessels serving the Ukrainian military.
