WARSAW, Feb. 20 - Poland's energy security will remain largely unaffected if Russian Gazprom takes over Ukraine's natural-gas distribution system, though the move could lead to further deterioration of bilateral relations with Moscow, analysts said.

"[The move] will have no major impact on our energy security," Tomasz Chmal, an expert at Sobieski Institute, an energy think-tank, said Monday. "From the political point of view, it creates room for higher uncertainty."
