On Wednesday, The Wall Street Journal reported, citing diplomatic and military sources, that NATO is considering sending a battalion of up to 1,000 soldiers to Poland and the Baltic countries of Estonia, Latvia, and Lithuania, as well as deploying a single battalion for the entire region.
"Allies will continue to discuss the next steps to deal with security challenges as we prepare for NATO summit in Warsaw next July, including how to further strengthen collective defense through long-term adaption. But we are not discussing at this stage specific options," Romero said.
A source in a European ally's mission to NATO confirmed to Sputnik that no specific discussions of NATO troops increase were taking place.
The source added that any changes in NATO-Russia relations should stay strictly within the rules of the NATO-Russia Founding Act.
The plan envisages a rotational presence of NATO forces in its eastern allies, the creation of six new small headquarters in the region, as well as an intensive exercise program.
Earlier on Thursday, Kremlin spokesman Dmitry Peskov said Moscow has repeatedly warned about the inappropriateness and threat posed by an increase in the number of NATO troops positioned along Russia's western border.
