NATO will enhance its battle groups in the eastern part of the alliance up to brigade levels, NATO Secretary-General Jens Stoltenberg announced Monday.
"We will increase the number of high readiness forces to well over 300,000," he said at a news conference in Brussels.
This includes "more pre-positioned equipment and stockpiles of military supplies; more forward-deployed capabilities, like air defense; strengthened command and control, and upgraded defense plans with forces pre-assigned to defend specific allies," Stoltenberg added.
The NATO Response Force comprises around 40,000 troops, according to the NATO website.
"These troops will exercise together with home defense forces. And they will become familiar with local terrain, facilities, and our new pre-positioned stocks so that they can respond smoothly and swiftly to any emergency," Stoltenberg went on to say, stressing that "this constitutes the biggest overhaul of our collective deterrence and defense since the Cold War."
These comments come ahead of the NATO summit that will be held in Madrid this week.
The summit will be "transformative," with many important decisions, including on a new "strategic concept for a new security reality," Stoltenberg said Monday, adding that this will include a discussion on China "for the first time."
"Our new concept will guide us in an era of strategic competition. I expect it will make clear that allies consider Russia as the most significant and direct threat to our security," Stoltenberg said. "It will address China for the first time. And the challenges that Beijing poses to our security, interests, and values."
US President Joe Biden and his Chinese counterpart Xi Jinping will likely speak in the coming weeks, the White House said. While there is no timeframe, the conversation will not happen immediately after the G7 meet, where China was a primary topic of discussion, US national security adviser Jake Sullivan told reporters in Germany.
