Here’s one of many reasons why Ukraine is struggling financially and dependent on Western loans: Its government is losing $4.8 billion a year due to corruption in the customs service alone, according to a report by German newspaper Süddeutsche Zeitung published on Aug.6.

Since 2015, Ukraine has received $8.7 billion in low-interest loans under the $17.5 bailout program it signed with the International Monetary Fund that year. It has used the money to reduce the budget deficit, boost international reserves and other authorized spending.
