Other factors behind the recession were the falling prices of metallurgical products on the global market and logistic problems, it said.

In March, the militants took over the Ukrainian-controlled businesses operating in the occupied areas after a group of Ukrainian activists had blocked the movements of trains transporting coal and other raw products from the non-government controlled areas.

In 2016, Ukraine's metallurgical industry recovered from a two-year recession, with all three key branches showing a growth of between 5.5% and 7.8%.

Metallurgy generates more than 20% of Ukraine's exports revenue and provides about 300,000 jobs.
