KHARKIV, Dec 13 - Both Poland and Ukraine are against the construction of the Nord Stream 2 gas pipeline, Polish President Andrzej Duda said.

"Poland's position on the Nord Stream 2 issue remains unchanged. We are absolutely against this investment, we believe that it tramples on European regulations and that it is at odds with the European Union's interests, and here our positions [with Ukraine] have been definite, identical, and invariable from the very beginning," Duda said at a joint press briefing with Ukrainian President Petro Poroshenko in Kharkiv on Wednesday.
