Abe spoke to reporters Tuesday after a phone conversation with the American president.
South Korean President Moon Jae-in vowed to prevent war at all costs and told the United States that it would need Seoul's permission to attack North Korea, Reuters reported. Bannon was quoted as saying there's no military solution to the threat posed by North Korea and its nuclear ambitions, despite the president's recent pledge to answer further aggression with "fire and fury".
Next week's start of annual US-South Korean military exercises that enrage the North each year could make diplomacy even more hard. That appeared to signal a path to defuse the crisis.
Moon's promise came at a time of heightened tension between the United States and North Korea, which earlier in August threatened with a plan to launch four missiles towards areas close to Guam, where important American military bases are stationed.
North Korean officials then threatened to launch four missiles into the sea off the coast of Guam.
The U.S. cited concern over unsafe intercepts of its aircraft by China, and a lack of transparency in military spending.
"I can confidently say there will not be war again on the Korean Peninsula".
The announcement came as North Korea reportedly said leader Kim Jong-un was briefed on plans for missile tests near Guam.
The combined military exercise, set to begin August 21, could trigger a conflict, according to Pyongyang's state-controlled news agency KCNA.
As Quartz has written, with tensions high on the Korean Peninsula, a small military incident could rapidly escalate into a full-blown war. He also said, "North Korea must at least end additional provocations to create the mood for dialogue".
South Korean President Moon Jae-In declared today that there will be no war on the Korean peninsula during a press conference to mark his government's hundred days in office.
The Ulchi-Freedom Guardian exercises, scheduled to begin Monday, are "not now on the table as part of the negotiation at any level", said Joseph Dunford, chairman of the US Joint Chiefs of Staff, as quoted by Reuters.
