The Air Forces of both countries "will continue to strengthen joint drills to have strong response capabilities and readiness against North Korea's nuclear and missile threats," it said in a statement.
Last year, North Korea conducted a record number of ballistic missile tests, which are banned by U.N. Security Council resolutions. It was also observed reopening its shuttered nuclear weapons test site, raising expectations of a nuclear test for the first time since 2017.
On Thursday, North Korea's Foreign Ministry said earlier drills by the United States and its allies had reached an "extreme red line" and threatened to turn the peninsula into a "huge war arsenal and a more critical war zone."
Pyongyang was not interested in dialogue as long as Washington pursued hostile policies, said the statement carried by North Korea's state news agency.
