United States (US) Secretary of State Marco Rubio said after a meeting with Group of Twenty (G20) foreign ministers in Atlanta that President Donald Trump remains open to talks with North Korean leader Kim Jong Un, but no meeting has been scheduled.

North Korea denounced the combined South Korea–US Iron Mace exercise, which integrates South Korean conventional and US nuclear capabilities. The exercise was a tabletop simulation at the Joint Chiefs of Staff headquarters in Seoul, from September 29 to October 2, to deter North Korean threats. Pyongyang said its nuclear deterrence will grow stronger at an ever faster pace.
