OTHER DEVELOPMENTS:

BRUSSELS — China has reacted to NATO naming it as a security challenge by calling the Western military alliance a “Cold War remnant” that is “smearing” Beijing’s international reputation.

On Wednesday, NATO issued its updated Strategic Concept, the document that lays out its top security threats for the coming decade. While Russia was named its top threat, NATO included China for the first time.

It said that China “strives to subvert the rules-based international order, including in the space, cyber and maritime domains” and warned of its close ties with Moscow.

A statement released by China’s Mission to the European Union on Thursday responded: “Since NATO positions China as a ‘systemic challenge,’ we have to pay close attention and respond in a coordinated way. When it comes to acts that undermine China’s interests, we will make firm and strong responses.”

China insisted that it promotes peace through its collaboration with the United Nations and its foreign development projects.

It called the 30-nation alliance a source of instability.

“NATO claims itself to be a defensive organization that upholds the rules-based international order, but it has bypassed the U.N. Security Council and waged wars against sovereign states, creating huge casualties and leaving tens of millions displaced,” it said.
