Senior Ukrainian officials will meet with the Biden administration this week to present a list of targets in Russia, a Ukrainian lawmaker said CNNThe aim is to persuade the US to relax its restrictions on the use of American weapons against Moscow.

Andriy Yermak, director of the Ukrainian presidential office, and Defense Minister Rustem Umerov will meet with U.S. officials “to try to specifically persuade the White House to lift restrictions on long-range weapons attacks on Russian territory,” the lawmakers said.

“They will present a list of priority targets without which it will be difficult to change the course of the war in Ukraine’s favor.”

US officials informed CNN that Umerov will meet with Defense Secretary Lloyd Austin on Friday.

On previous trips to Washington, Yermak met with Secretary of State Antony Blinken and National Security Advisor Jake Sullivan.

Russia: US cannot be trusted to ban long-range weapons against Ukraine

Washington’s claims that it would prohibit Ukraine from using US long-range weapons for deep strikes on Russian territory are not trustworthy, Moscow’s ambassador to the US, Anatoly Antonov, said last week.

Ukrainian President Volodymyr Zelensky has resumed talks with the United States to allow Kiev troops to use long-range weapons during their ongoing incursion into the Kursk region.

Last week, however, the Pentagon reiterated its stance to prevent the former Soviet state from using US-supplied ATACMS missiles, which have a range of up to 300 kilometers, to attack Russian territory.

US officials “seem to be constantly teasing us by saying that it is supposedly not allowed to attack Russian territory with long-range systems today,” Antonov told reporters on Friday, adding: “In reality, they are essentially preparing the ground for simply lifting all existing restrictions at some point.”

The Russian envoy based his judgment on the US’s previous support for Kiev during the war with Moscow and expressed his certainty that TASS that Ukraine would “fight us with (long-range) weapons of American production,” adding: “Where exactly will this happen? We can neither say nor predict that.”

The ambassador described the administration of US President Joe Biden as unpredictable and stressed: “There is no guarantee that the whole world will not change tomorrow when you and I wake up. How Americans will behave in this situation is very difficult to predict.”

Antonov stressed that Russia must therefore “act decisively and increase its military-industrial potential, because only our army and navy will be able to protect our country.”
