"The fact that we have not had military losses for several days... Is a clear indication of a gradual de-escalation," Poroshenko told Ukraine's private 1+1 television network.
Poroshenko's remarks tallied with those of international ceasefire monitors, who said Thursday that the February 12 truce was "broadly" holding up, despite sporadic clashes in a handful of flashpoints.
Poroshenko said he was confident that Ukraine's appeals to the West for arms -- which so far have fallen on deaf ears -- would receive a favourable response if the rebels mounted a renewed offensive.
On Wednesday the US announced plans to send Kiev military equipment worth USD 75 billion -- but not weapons.
