Ukraine struck several Russian military targets this week, including a Be-200 amphibious aircraft, President Volodymyr Zelensky said on May 16.
"Probably they need more people to send to the war in Ukraine," Moldovan President Maia Sandu said.
Andrii Kovalenko, an official at Ukraine's National Security and Defense Council, described the facility as "a critical component" of Russia's defense-industrial complex.
The Russian side has not commented on whether Ukraine transferred the bodies of Russian soldiers in return.
The Russian and Chinese presidents will discuss bilateral relations and ways to deepen the countries' "partnership and strategic cooperation."
