Ukrainian presidential adviser Mykhaylo Podolyak says Ukraine must score a victory in the Donbass region before any potential meeting between Zelensky and Putin.
"Ukraine is ready for big battles. Ukraine must win them, including in the Donbass. And once that happens, Ukraine will have a more powerful negotiating position, which will allow it to dictate certain conditions," he said on national television, as quoted by Interfax-Ukraine.
"After that the presidents will meet. It could take two weeks, three," he added.
