BRUSSELS, March 5 – The option of terminating transit of natural gas across Ukraine in 2020 by Russia's Gazprom after the completion of the Nord Stream 2 pipeline is a base scenario, Naftogaz Ukrayiny COO Yuriy Vitrenko said.

This is the base option and we have to deal with it, he said in Brussels during the discussion entitled "The Future of Ukraine's Gas Transit Route and European Energy Security."
