It follows months of escalating furious rhetoric exchanged between the US and North Korea, with both sides threatening war after secretive dictator Kim Jong-un tested six missiles in as many months.
Some South Koreans worry the provocative President will spark a global conflict with his visit to North Korea’s neighbours and allies after the two countries already threatened to destroy one another.
Former UN Secretary General Ban Ki-moon has warned threats of war between the two countries mark “a critical time” for the world, but forming alliances with countries like the ones President Trump will visit on this tour could be the antidote.
Mr Ban said that Japan, China and South Korea need to “exercise maximum pressure” so that North Korea realise they are not able to “go against the will of four international communities”.
He told CNBC: “This is the worst security situation since the end of the Korean war.”
Mr Ban called for unity between the four nations and said: “I appreciate President Trump’s initiative to visit Korea, Japan and China at this very critical time. I sincerely hope the leaders of three, four countries will come out with the common strategy.
“And sending resolute and unified and determined and very strong message that such North Korean defiant behaviour, breaking all norms of international community will never be tolerated.”
