Iryna Heraschenko, a representative of Ukraine in the working sub-group on humanitarian issues of the trilateral contract group, said Ukraine will regard any attempts to erode this format as an intention to revise the Minsk agreements.

"Russia is trying really hard to erode this format. Essentially, Ukraine will regard any attempt to erode this format as an attempt to revise the Minsk agreements," Heraschenko said at a meeting of the interparliamentary council Ukraine-NATO in Kyiv on Monday.
