KYIV, Dec 5 - Cargo flow at the Ukrainian ports in the Sea of Azov have more than halved, and the ports have had to shift to a four-day workweek and cut the number of employees, Ukrainian Infrastructure Minister Volodymyr Omelyan wrote on Facebook.

"As we expected, Moscow is undertaking the manual regulation of access to the Ukrainian seaports in the Sea of Azov for trade ships according to the Kremlin's long-standing principle 'it's up to me to decide.' ... As a result of this approach, two Ukrainian ports had to more than halve their cargo flow and had to shift to a four-day workweek and slash the number of employees," Omelyan wrote.
