MOSCOW, April 18 (Xinhua) -- Ukraine peace talks remain difficult while some progress has been made, Kremlin spokesperson Dmitry Peskov said Friday.

Peskov said Russia seeks to resolve the Ukraine conflict taking into account its interests.

The spokesperson noted that progress had been made, such as the temporary halt of strikes on energy infrastructure.

Commenting on the ceasefire, Peskov said that the month-long truce has expired, and Russian President Vladimir Putin has not issued any further orders.

After their separate talks with U.S. delegations in late March, Russia and Ukraine agreed to develop measures implementing a 30-day ban on striking each other's energy facilities, which was first proposed on March 18. ■
