Ukraine's Economy Did Not Get Far Since The 1990s

I was surprised when I saw it. Ukraine's economy is not as active as it was in the early 1990s. Number of shipments is still much lower than it was in the early 1990s, reported by the Ukraine's State Statistics Committtee. Here is a very interesting graph that gives you a breakdown of quantity of shipments across Ukraine by type of transportation: air, water (sea and river), and ground (car and train). I wonder what explains a smaller number of shipments now as compared to the early 1990s.
