More Tit for Tat WTO Disputes

I know that at least two of you readers out there have been keeping an eye on tit for tat WTO disputes.  Here's another.

Ukraine - Anti-Dumping Measures on Ammonium Nitrate

.

And now on October 21, Ukraine requested consultations with Russia in

Russia - Measures Affecting the Importation of Railway Equipment and Parts Thereof

.

Obviously, there are some other issues between Ukraine and Russia that are part of the mix as well.
