Spain's Defense Minister Margarita Robles said this on Thursday, January 20, according to Reuters.
A mine-sweeper is already en route and a frigate will sail within three or four days, Robles told reporters. The Madrid government is also considering sending fighter jets to Bulgaria, she said.
"Russia cannot tell any country what to do, so NATO will protect and defend the sovereignty of any country that can or wants to join NATO," Robles said.
Spain's preference was for an "exclusively diplomatic response" to resolving the conflict, she added.
The Spanish contribution to the NATO military deployment in Eastern Europe comes after Foreign Minister Jose Manuel Albares and U.S. Secretary of State Antony Blinken discussed a coordinated response to the threat to Ukraine from Russia at a meeting in Washington on Tuesday.
Denmark said it was sending a frigate to the Baltic Sea this week and French President Emmanuel Macron has offered to send troops to Romania. Further troop decisions could be made as early as a NATO summit in Madrid in June, diplomats and officials said.
