"The Ukrainian officials are attempting to make ineffective the plan for withdrawal of [heavy military] equipment starting on February 22, which has been developed by the Joint Coordination Centre and signed by the [conflicting] sides," Denis Pushilin and Vladislav Deinego said in a joint statement after the latest round of teleconferencing talks on the Ukrainian ceasefire.
The envoys said the Donbas militia has pulled out some 400 pieces of heavy military equipment from the separation line in eastern Ukraine since February 22, while Kiev-led forces have not moved a single piece.
"After today's meeting of the Contact Group we can see the tendency, which puts the negotiability of the Ukrainian side under question: Kiev makes yet another attempt to revoke a signature of its representative," Pushilin and Deinego said.
Under the agreement reached in Minsk, Kiev and independence supporters must withdraw their heavy artillery to a distance of 30-85 miles from the line separating the government forces and the DPR and LPR militia.
However, Kiev military spokesman, Andriy Lysenko, said on Tuesday that government troops could start a heavy weaponry pullout only if the ceasefire in eastern Ukraine remained stable for at least 48 hours.
The eastern Ukrainian envoys have nevertheless expressed hope that Kiev will begin a weaponry withdrawal in accordance with the Minsk agreements.
