Trump became the first sitting U.S. president to set foot in North Korea on Sunday when he met Kim in the Demilitarized Zone (DMZ) between the two Koreas and agreed to resume stalled nuclear talks.

North Korean leader Kim Jong Un and Russian President Vladimir Putin will meet on Thursday in the Russian Pacific port of Vladivostok to discuss the international standoff over Pyongyang's nuclear program, a Kremlin official said.

North Korean leader Kim Jong Un arrived Sunday in Singapore ahead of one of the most unusual and highly anticipated summits in recent world history, a sit-down with President Donald Trump meant to settle a standoff over Pyongyang’s nuclear bomb arsenal.
