Gen. Valery Zaluzhny, Ukraine's military chief, told the Post that Ukrainian forces needed more specialist mine-clearing equipment.
A Ukrainian official told the Post that it had only received around 15% of the specialist de-mining equipment it had requested from Western allies.
A US official responded that it would provide all the equipment requested, but there were problems providing it on the scale requested in a timely way.
Ukraine launched its much-anticipated counteroffensive in June, seeking to drive Russian forces back from territory it occupies in south and east Ukraine.
So far Ukraine has made limited advances, with Russian forces having dug heavily fortified positions protected by landmines during the winter.
