According to him, the working group on "reintegration" has already begun to discuss this issue.

“Among the main ideas is the need to develop a strategy for reintegrating the occupied territories with an action plan that would be regularly reviewed,” Ryaboshapka said.

He said that it was planned to prepare the concept of “transitional justice”.

“In addition, one of the priorities is to finally ratify the Rome Statute of the International Criminal Court, signed almost 20 years ago,” the official said.

Earlier, Ukrainian leader Vladimir Zelensky expressed confidence that Crimea would “return” to Ukraine.

Crimea became the Russian region after a referendum held in March 2014, in which most residents spoke out for reunification with Russia.
