This was announced by Deputy Head of the Presidential Administration of Ukraine Kostiantyn Yelisшeiev, Censor.NET reports referring to Ukrainski Novyny.
"It is crucial for us that the OSCE be provided with access to all areas. If not, there will be a reason for convening a tripartite contact group to tackle the issue. If the issue is not settled, the party concerned is to be held liable in terms of strengthening sanctions," he said.
Yelisшeiev noted that an important achievement of the Normandy format talks was agreeing on the access of OSCE observers to the Ukrainian-Russian border.
Until now, he said, such an access had not been granted.
The deputy head of the administration said that Ukraine, France and Germany intend no review of sanctions against Russia.
According to him, the sanctions will apply until Russia fulfills the agreements reached in Minsk (Belarus) on Feb. 12.
"There have been attempts by Russia to mitigate EU's sanctions. However, the sanctions will be effective until the Minsk agreements are fully fulfilled," he said.
